Introduction, Design And Features
The gaming keyboard market seems to rigorously follow a common rule of consumer products - more is more. If a keyboard is for gamers it should include lots of fancy gaming related features, and the more that are included, the more hardcore the keyboard. Macro buttons, customizable back-lighting and LCD screens are all features of modern gaming keyboards–and you don’t see many companies going the other direction.
But there are products that buck the trend. One of them is the CMStorm QuickFire Rapid, a mechanical gaming keyboard that became available in North America earlier this year. Unlike most competitors, the QuickFire rapid cuts features instead of adding them. Back-lighting? Macro keys? You’re kidding me, right? This keyboard doesn’t even include a numpad.
Cooler Master (the company behind CMStorm) has not cut out the features that matter, however. This keyboard comes with Cherry MX keys (the blue variant, in this case) and also supports PS/2 connections for full NKRO. For those who’ve seen the light of day recently, this gobbly gook means the QuickFire Rapid scans key activation individually and therefore can detect new key activations even when other keys are still depressed. It’s a feature hardcore gamers love because of their tendency to press multiple keys simultaneously.
Cutting back on unneeded features has a notable side effect–it reduces price. Currently this keyboard is available for $79.99 at retail or as low as $65 on Amazon.com. Only Razor’s bare-bones version of the BlackWidow keyboard sells for less, and it only beats the QuickFire by $5 dollars.
So can you really buy a decent gaming keyboard for $65, and will you miss the numpad? Let’s find out.
An HTPC Perspective on home theater PC technology
We conducted a reader survey a few weeks ago, and one of the tech topics that received a surprising amount of interest in was HTPC coverage. You, our awesome readers, wanted to know more about the hardware and software behind them. I’ll admit that I was ardent about the prospects of talking HTPCs with you. As a relatively new entrant to that area of tech myself, I was excited to cover it, and give you more coverage on a topic you wanted to see more of!
Today we won't be talking about home theater PCs in the sense of a computer in the living room AV rack (Ryan covered that earlier this week), but rather a related technology that makes the HTPC possible: the CableCARD-equipped TV tuner.
I will forewarn you that this article is quite a bit more informal than my usual writings, especially if you only follow my PC Perspective postings. In the future, it may not be that way, but I wanted to give some backstory and some personal thoughts on the matter to illustrate how I got into rolling my own DVR and why I’m excited about it (mainly: it saves money and is very flexible).
Despite my previous attempts to “cut the cord” and use only Internet-based services for television, me and my girlfriend slowly but surely made our way back to cable TV. For about a year we survived on Netflix, Hulu, and the various networks’ streaming videos on their respective websites but as the delays between a shows airing and web streaming availability increased and Netflix instant Streaming started losing content the price of cable started to look increasingly acceptable.
She was probably the first one to feel the effects of a lack of new content – especially with a newfound love for a rather odd show called True Blood. It was at some point thereafter, once she had caught up with as many seasons offered on Netflix of various shows as possible that she broke down and ordered U-Verse. U-Verse is an interesting setup of television delivery using internet protocol (IPTV). While we did have some issues at first with the Residential Gateway and signal levels, it was eventually sorted out and it was an okay setup. It offered a lot of channels – with many in HD. In the end though, after the promotional period was up, it got very expensive to stay subscribed to. Also, because it was IPTV, it was not as flexible as traditional cable as far as adding extra televisions and the DVR functionality. Further, the image quality for the HD streams, while much better than SD, was not up to par with the cable and satellite feeds I’ve seen.
Being with Comcast for Internet for about three years now, I’ve been fairly happy with it. One day I saw a promotion for currently subscribed customers for TV + Blast internet for $80, which was only about $20 more than I was paying each month for its Performance tier.
After a week of hell Therefore, I decided to sign up for it. Only, I did not want to rent a Comcast box, so I went searching for alternatives.
Enter the elusive and never advertised CableCARD
It was during this search that I learned a great deal about CableCARDs and the really cool things that they enabled. Thanks to the FCC, cable television providers in the United States have to give their customers an option other than renting a cable box for a monthly fee – customers have to be able to bring their own equipment if they wish (they can still charge you for the CableCARD but at a reduced rate, and not all cable companies charge a fee for them). But what is a CableCARD? In short, it is a small card that resembles a PCMIA expansion card – a connector that can commonly be found in older laptops (think Windows XP-era). It is to be paired with a CableCARD tuner and acts as the key to decrypt the encrypted television stations in your particular subscriber package. They are added much like a customer-owned modem is, by giving the cable company some numbers on the bottom of the card that act as a unique identifier. The cable company then connects that particular card to your account and sends it a profile of what channels you are allowed to tune into.
There are some drawbacks, however. Mainly that On Demand does not work with most CableCARDS. Do note that this is actually not a CableCARD hardware issue, but a support issue on the cable company side. You could, at least in theory, get a CableCARD and tuner that could tune in On Demand content, but right now that functionality seems to be limited to some Tivos and the rental cable boxes (paradoxically some of those are actually CableCARD-equipped). It’s an unfortunate situation, but here’s hoping that it is supported in the future. Also, if you do jump into the world of CableCARDs, it is likely that you will find yourself in a situation where you know more about them than the cable installer as cable companies do not advertise them, and only a small number of employees are trained on them. Don’t be too hard on the cable tech though, it's primarily because cable companies would rather rent you a (expensive) box, and a very small number of people actually know about and need a tech to support the technology. I was lucky enough to get one of the “CableCARD guys,” on my first install, but I’ve also gotten techs that have never seen one before and it made for an interesting conversation piece as they diagnosed signal levels for the cable modem (heh). Basically, patience is key when activating your CableCARD, and I highly recommend asking around forums like DSLReports for the specific number(s) to call to get to the tier 2 techs that are familiar with CableCARDs for your specific provider when calling to activate it if you opt to do a self-install. Even then, you may run into issues. For example, something went wrong with activation on the server side at Comcast so it took a couple of hours for them to essentially unlock all of my HD channels during my install.
Following the successful launch of its HS1 headset, Corsair has come back with a Vengeance line of gaming peripherals including three new headsets. Included in the new lineup are the 1100, 1300, and 1500 gaming headsets.
The Vengeance 1100 is the smallest of the three gaming headsets, and features a behind-the-head headphone design using 40mm drivers and an unidirectional boom microphone extending from the left speaker. The 1100 can be connected via two analog 3.5mm audio jacks or by USB with the included adapter.
An overview of Thunderbolt Technology
The promise of Thunderbolt connectivity has been around for a couple of years now. Today, Thunderbolt is finally finding its way to the PC platform in the form of motherboards from ASUS and MSI. First unveiled as "Light Peak" at the Intel Developer Forum in 2009, the technology started out as a way to connect multiple devices to a system over a fiber optic cable (hence the 'light' in the name), though the final products have changed the implementation slightly.
The first prototype implementations actually used a USB-style connection and interface. It further required fiber optic cables. When it was renamed to Thunderbolt and then released in conjunction with a new lineup of Apple MacBook laptops, not only did the physical interface move to a mini-DisplayPort connection but the cable was made to use copper rather than fiber. Without diving too far into the reasons and benefits of either direction, the fact is that the copper cables allow for modest power transfer and are much cheaper than fiber optic variants would be.
Thunderbolt's base technology remains the same, however. It is a transfer standard that allows for 10 Gbps of bandwidth for each channel (bi-directional) and concurrently supports both data and display connections. The actual interface for the data path is based on PCI Express and connected devices actually appear to Windows as if they are internally connected to the system which can offer some interesting benefits – and headaches – for hardware developers. The display connection uses the DisplayPort standard and can be used along with the data connection without affecting bandwidth levels or performance.
For current Intel processor implementations, the Thunderbolt connection is supported by a separate controller chip on the motherboard (or a riser card) – and some routing is required for correct usage. The Thunderbolt controller does not actually include a graphics controller, so it must be fed an output from another graphics processor, obviously in this case directly from the Ivy Bridge / Sandy Bridge processors. In theory, these could be from other controllers, but with the ubiquitous nature of integrated processor graphics on IVB and SNB processors, this is going to be the implementation going forward according to motherboard and system designers.
A few weeks ago I witnessed a technology demo by Western Digital. I arrived expecting to see something storage related, but what I saw was completely different - a new line of routers!
The new 'My Net' series of Western Digital routers are intended to cover the mid to high end of the home usage spectrum. Models start with 4 ports of Fast Ethernet and scale all the way up to 7x GigE switching. All models support some form of simultaneous dual band (2.4 and 5 GHz), with a minimum of 2x2 and scaling up to 3x3 configurations (more detail / explanation on that later).
NVIDIA puts its head in the clouds
Today at the 2012 NVIDIA GPU Technology Conference (GTC), NVIDIA took the wraps off a new cloud gaming technology that promises to reduce latency and improve the quality of streaming gaming using the power of NVIDIA GPUs. Dubbed GeForce GRID, NVIDIA is offering the technology to online services like Gaikai and OTOY.
The goal of GRID is to bring the promise of "console quality" gaming to every device a user has. The term "console quality" is kind of important here as NVIDIA is trying desperately to not upset all the PC gamers that purchase high-margin GeForce products. The goal of GRID is pretty simple though and should be seen as an evolution of the online streaming gaming that we have covered in the past–like OnLive. Being able to play high quality games on your TV, your computer, your tablet or even your phone without the need for high-performance and power hungry graphics processors through streaming services is what many believe the future of gaming is all about.
GRID starts with the Kepler GPU - what NVIDIA is now dubbing the first "cloud GPU" - that has the capability to virtualize graphics processing while being power efficient. The inclusion of a hardware fixed-function video encoder is important as well as it will aid in the process of compressing images that are delivered over the Internet by the streaming gaming service.
This diagram shows us how the Kepler GPU handles and accelerates the processing required for online gaming services. On the server side, the necessary process for an image to find its way to the user is more than just a simple render to a frame buffer. In current cloud gaming scenarios the frame buffer would have to be copied to the main system memory, compressed on the CPU and then sent via the network connection. With NVIDIA's GRID technology that capture and compression happens on the GPU memory and thus can be on its way to the gamer faster.
The results are H.264 streams that are compressed quickly and efficiently to be sent out over the network and return to the end user on whatever device they are using.
Infectious fear is infectious
PCMag and others have released articles based on a blog post from Sophos. The original post discussed how frequently malware designed for Windows is found on Mac computers. What these articles mostly demonstrate is that we really need to understand security: what it is, and why it matters. The largest threats to security are complacency and misunderstanding; users need to grasp the problem rather than have it burried under weak analogies and illusions of software crutches.
Your data and computational ability can be very valuable to people looking to exploit it.
The point of security is not to avoid malware, nor is it to remove it if you failed to avoid it. Those actions are absolutely necessary components of security -- do those things -- but they are not the goal of security. The goal of security is to retain control of what is yours. At the same time, be a good neighbor and make it easier for others to do the same with what is theirs.
Your responsibility extends far beyond just keeping a current antivirus subscription.
The problem goes far beyond throwing stones...
The distinction is subtle.
Your operating system is irrelevant. You could run Windows, Mac, Android, iOS, the ‘nixes, or whatever else. Every useful operating system has vulnerabilities and run vulnerable applications. The user is also very often tricked into loading untrusted code either directly or delivering it within data to a vulnerable application.
Blindly fearing malware -- such as what would happen if someone were to draw parallels to Chlamydia -- does not help you to understand it. There are reasons why malware exists; there are certain things which malware is capable of; and there are certain things which malware is not.
The single biggest threat to security is complacency. Your information is valuable and you are responsible to prevent it from being exploited. The addition of a computer does not change the fundamental problem. Use the same caution on your computer and mobile devices as you should on the phone or in person. You would not leave your credit card information on a park bench unmonitored.

Microsoft's juggernaut Windows operating system powers on with the company preparing Windows 7's successor in Windows 8. The new operating system (OS) was first released for public consumption during the last BUILD conference in the form of a "Developer Preview." This release was mainly intended for software developers to start to get a feel for the OS and its new features, but many consumers and technology enthusiasts also took a peek at the OS to get an idea of where MS was going with its next OS.
Coinciding with Mobile World Congress (MWC) 2012, Microsoft released the next iteration of the in progress OS, and this time it is aimed at getting consumer feedback. The aptly named Consumer Preview build is now available for download by anyone interested.
Windows 8 Consumer Preview Desktop
The question many consumers and enthusiasts are likely asking; however, is what to do with the MS provided ISO, and what the safest and easiest method for testing the beta operating system is. One appropriate answer, and the method covered in this guide, is to use a virtual machine program to test the Windows 8 Consumer Preview inside a VM without needing to muck with or worry about effecting your existing system or settings. Installing to bare hardware will always be faster, but if you upgrade to Windows 8 CP from Windows 7, you will not be able to go back once the beta period is over. By installing Windows 8 Consumer Preview inside a virtual machine will allow you to test out the operating system in a secure environment, and if you have a recent machine with at least 4 GB of RAM, performance of the OS should be sufficient to get an idea of the new OS and whether you want to pursue a bare hardware full install.
I expect that many users are going to be curious about the new build as the Windows 8 OS has ignited several heated debates among enthusiasts concerning the direction Microsoft is going. The new Metro interface, removal of Start Menu, and the overhauled Windows logo are three of the major concerns users have raised, for example.
The specific program in question that we will be using is Oracle's VirtualBox software, which is a free VM host that is very easy to setup and use. Another alternative is VMWare, and the setup process will be very similar (though the exact steps and settings will differ slightly). This guide will show you how to go from the Windows 8 ISO to a fully functional installation inside a VirtualBox virtual machine. If you are familiar with setting up a new VirtualBox VM, you can safely skip those steps. I felt it prudent to go through the entire process; however, for those new to VirtualBox that wish to try out the new Microsoft OS.
Rosewill produces a whole lineup of products with seemingly incongruous variety. You can get matching brands for your blood pressure monitor, your wine opener, your DSLR bag, and your computer power supply. The vast majority of Rosewill's distribution flows through Newegg.
Their RK-9000 mechanical keyboard was manufactured by CoStar under the Rosewill branding. With that product, they brought a high quality mechanical keyboard to North America for a very decent price of just under a hundred dollars. For what might as well be considered a Filco keyboard, that is an outstanding price. It did not have media keys; it did not have backlighting; but it was a solid keyboard which felt great to type on and had outstanding performance.
Check out our video review of the Rosewill RK-9000 second generation and read on for the written review
At some point Rosewill decided to discontinue the RK-9000 without an official announcement. Beyond a sudden and sustained drop in availability, there was no evidence that the keyboard was no longer produced. A few silent months went by until Rosewill officially announced a second generation of RK-9000 mechanical keyboards. It was then clear why the RK-9000 was discontinued: it was being replaced and updated.
We were approached by the company to conduct a review of their recently released mechanical keyboards. Included was not just the Cherry MX Blue switched RK-9000, but also its three newly introduced siblings: the MX Brown switched RK-9000BR, the MX Black switched RK-9000BL, and the MX Red switched RK-9000RE. A little under three months ago we have received the review units and have been in the process of testing them ever since.
What Rosewill was unaware of was that I am a proud owner of the original RK-9000 keyboard. This review is more than a review of Rosewill’s new products, but also will be a comparison between the new product and their original offering. Despite sharing a Newegg product page with its ancestor, the new keyboard is not identical. For good measure, I also have a Razer BlackWidow Ultimate lying around -- slightly dilute the oversaturation of the letter R in tested product names… albeit, not the company names.
A new contender has enterkeyed.
If you happen to have an original RK-9000, is it time for an upgrade? If you are interested in all of the hoopla about mechanical keyboards, is this the correct time and place to dive in?
AMD Gives a Glimpse of the Near Future
AMD has released an updated roadmap for these next two years, and the information contained within is quite revealing of where AMD is going and how they are shifting their lineup to be less dependent on a single manufacturer. The Financial Analyst Day has brought a few surprises of where AMD is headed, and how they will get there. Rory Read and Mark Papermaster have brought a new level of energy to the company that seemingly has been either absent or muted. Sometimes a new set of eyes on a problem, or in this case the attitudes and culture of a company, can bring about significant changes for the positive. From what we have seen so far from Rory and company is a new energy and direction for AMD. While AMD is still sticking to their roots, they are looking to further expand upon their expertise in some areas, all the while being flexible enough to license products from other companies that are far enough away from AMD's core competence that it pays to license rather than force engineers to re-invent the wheel.
The roadmaps cover graphics, desktop, mobile, and server products through 2013.
This first slide is a snapshot of the current and upcoming APU lineup. Southern Islands is the codename for the recently released HD 7000 series of desktop parts. This will cover products from the 7700 level on up to the top end 7990. Of great interest are the Brazos 2.0 and Hondo chips. AMD had cancelled the "Krishna" series of chips which would have been based on Bobcat cores up to 4 on 28 nm. Details are still pending, but it seems Brazos 2.0 will still be 40 nm parts but much more refined so they can be clocked higher and still pull less power. Hondo looks to be the basic Brazos core, but for Ultra Low Power (lower clocks, possibly disabled units, etc.) which would presumably scale to 5 watts and possibly lower.
As the neighborhoods are adorned with lights and reindeer decorations, and the airwaves are ringing with Christmas carols, one realizes that it is that time of year again! Although December arrived much faster than any of us at PC Perspective expected, there is no doubt that time to purchase gifts is running short and this year is almost over.
In keeping with the holiday spirit, the PC Perspective team got into a discussion about items and services that we would want for Christmas and that we felt would make really great gifts for our loved ones. And thus the PC Perspective Holiday Gift Guide 2011 was born!
Introduction: Griefing the grieving
PC Gaming has been on its death bed for years -- if you believe the countless debates that have occurred most commonly over the last decade. The drum beat roared from the masses: “Why game on the PC anymore when you could just buy a console?” The focus of conversation was set upon the attack and defense of the PC as a viable platform at all, let alone the platform of choice. The question that swarms naggingly through my brain is quite the opposite: “In the long run, why game on a console?” The concept that consoles are better than PCs, given a fraction of the support that consoles receive, is about to die; console supporters are in various levels of grief.
U mad Mario Bros.?
I am an avid, though this editorial may suggest livid, video game supporter. My first exposure to video gaming was mixed between the Nintendo Entertainment System and the family 80286. I have equally fond memories with the keyboard as with the gamepad. The balance between console and PC was level throughout my life until just a few years ago when I carefully thought the situation over. The PC is now my platform of choice.
Introduction, Campaign Testing
As you might have noticed, we’re a bit excited about Battlefield 3 here at PC Perspective. It promised to pay attention to what PC gamers want, and shockingly, it has come through. Dedicated servers and huge multi-player matches are supported, and the browser based interface is excellent.
If we’re honest, a lot of our hearts have been stirred simply by the way the game looks. There aren’t many titles that really let a modern mid-range graphics card stretch its legs, even at 1080p resolution. Battlefield 3, however, can be demanding - and it looks beautiful. Even with the presets at medium, it’s one of the most attractive games ever.
But what does this mean for laptops? Has the resident laptop reviewer at PC Perspective, I know that gaming remains a challenge. The advancements over the last few years have been spectacular, but even so, most of the laptops we test can’t run Just Cause 2 at a playable framerate even with all detail set to low and a resolution of just 1366x768.
To find out if mobile gamers were given consideration by the developers of Battlefield 3, I installed the game on three different laptops. The results only go to show how far mobile gaming has come, and has far it has to go.
The Mechanics of a Keyboard
During the duration of this review Razer announced two new mechanical keyboards, the BlackWidow Stealth and the BlackWidow Ultimate Stealth. This review is not for those products. Razer ninja’d me with stealth.
Keyboards are often overlooked during the purchase of a new computer; for many there does not appear to be any real difference between any two keyboards outside of wireless technology, backlighting, or extra keys. Those who game heavily or those who are typing enthusiasts for work or hobby might be in the market for a more personalized experience. There are whole categories of keyboard styles which allow a tailored solution to your personal style of use right down to the type of switch used to register a keystroke. Razer is no stranger to the production of input devices but they are stepping slightly out of their element with their recent products: The BlackWidow and the BlackWidow Ultimate, the first two from Razer which are based on mechanical switches.
Popping Razer’s CherryMX?
Membrane keyboards comprise the majority of the cheapest keyboards in the market with scissor-switch taking up the laptop and thin-profile keyboard market. Despite being cheap, these keyboards also have the advantage of being quite silent. A mechanical keyboard on the other hand uses an actual mechanical switch for each and every key. While such as system costs substantially more than a membrane keyboard the cost may be offset by the precision, the response, or the ability to type without “bottoming-out” each keystroke.
If the concept of a mechanical keyboard interests you then you will likely be dealing indirectly with Cherry Corp in the near future most likely with their MX line of switches. I say indirectly as Cherry avoids selling their keyboards except to business, industrial, governmental, and medical suppliers. For the rest of us there exist several companies who purchase large quantities of mechanical switches and manufactures keyboards with them for retail end-users. Some common mechanical keyboard brands include Filco, SteelSeries, XArmor, Optimus, Das Keyboard, and Ducky. Keep in mind that while there are many brands, almost all of their keyboards are produced by iOne, Datacomp, or Costar with a few exceptions. In our situation, Razer’s BlackWidow and BlackWidow Ultimate are produced by iOne who also produces the XArmor line of mechanical keyboards.
Read on for the rest of the review including benchmarks… yes that is possible!
True 5.1 Surround Sound Gaming Headset
Cooler Master is a household name in the PC case world, and an established player in the cooling industry. Not content with those two areas, Cooler Master has expanded into power supplies, keyboards, mousepads, and a plethora of other accessories where they apparently make a tidy bundle. Coolermaster is now moving into a new area; gaming audio. Under the “CM Storm” brand, Coolermaster is releasing its own set of cans.
We were sent a production quality sample, but it did not come in the retail box that is availble now.
Cooler Master is hoping to deliver a profound audio experience to users with their CM Storm Sirus (not Sirius mind) True 5.1 Surround Sound Gaming Headphones. The design and packaging certainly look impressive, but what counts in the end is the sound emanating from these products.
Last week we were in Dallas, Texas covering Quakecon 2011 as well as hosting our very own PC Perspective Hardware Workshop. While we had over 1100 attendees at the event and had a blast judging the case mod contest, one of the highlights of the event is always getting to sit down with John Carmack and pick his brain about topics of interest. We got about 30 minutes of John's time over the weekend and pestered him with questions about the GPU hardware race, how Intel's intergrated graphics (and AMD Fusion) fit in the future of PCs, the continuing debate about ray tracing, rasterization, voxels and infinite detail engines, key technologies for PC gamers like multi-display engines and a lot more!
One of our most read articles of all time was our previous interview with Carmack that focused a lot more on the ray tracing and rasterization debate. If you never read that, much of it is still very relevant today and is worth reading over.
This year though John has come full circle on several things including ray tracing, GPGPU workloads and even the advantages that console hardware has over PC gaming hardware.
Android 2.3 (Gingerbread)
The Nexus S 4G is a Google phone through and through. Following Google’s first hardware venture into the handset market, the Nexus One, this phone is how Google envisions the Gingerbread (Android 2.3) platform. Manufactured by Samsung, the Nexus S originally debuted as a GSM unlocked phone and on T-Mobile in the US earlier this year. Now, for the debut on CDMA networks, Samsung and Sprint have teamed together to add a 4G, WiMAX modem.
Because it is a Google tuned experience, the Nexus S 4G software is extremely polished, and provides a great user experience. Being the first phone to ship with Gingerbread, and still being one of the few phones shipping with it at this point in the game, it provides the absolute best small form-factor experience that Android is capable of.

A Headset for All Seasons
After being impressed by the Corsair SP2500 2.1 speaker system, I geared up to give their headphone audio a try. The technology that Corsair has implemented into their headphones certainly looks impressive, but only when we hear the sound will we know how well they accomplished this feat. Read on to see if Corsair can be the next Grado Labs in portable audio.A few weeks back I was able to listen to, and review, the SP2500 speakers from Corsair. These impressed me a great deal with their clarity, depth of sound, and overall representation in all three major aspects of computer audio (music, movies, and gaming). These were the first Corsair audio products that I had a chance to listen to, but they were not the first that Corsair had released at that time. Some months before the release of those speakers, Corsair had introduced the Gaming Audio HS1 USB headphones.
Pardon the quality of the picture, my camera is dying. The boys is well constructed and protects the headphones nicely.
The Relative Lack of SLI on AMD
Several years back we were introduced to the Lucid Hydra technology, and it seemed like an impressive multi-GPU implementation which could leverage the power of different video card combinations to improve performance over that of one card. Quite a few years have passed, and we have a handful of motherboards now supporting this technology. We take a look at the technology now implemented on the AMD side, and how it performs when using both AMD and NVIDIA based video cards.The first we heard of Lucid was a few years back when they showcased working silicon running multiple video cards together. Whether these were NVIDIA or ATI/AMD cards, Lucid had a way of allowing them to render a scene in a unique way, then composite the results to create a near seamless experience. It took some time before the first products hit the streets, and there is also quite a bit of controversy behind the actual implementation.
The primary rendering mode for both SLI and CrossFire is alternate frame rendering. Basically this allows each video card to process alternating frames, which theoretically can double performance. We have never seen true linear scaling in such situations, but it is not unheard of to reach 85% scaling or slightly more with the latest video cards on fast systems. Lucid does things a bit differently.
