Ryan was not the only one to test the ASUS ROG Swift PG278Q G-Sync monitor, Overclockers Club also received a model to test out. Their impressions of the 27" 2560 x 1440 TN panel were very similar, once they saw this monitor in action going back to their 30-inch 60Hz IPS monitor was not as enjoyable as once it was. The only bad thing they could say about the display was the MSRP, $800 is steep for any monitor and makes it rather difficult to even consider getting two or more of them for a multiple display system.
”When you get down to it, the facts are that even with a TN panel being used for the high refresh rate, the ASUS ROG Swift PG278Q G-Sync monitor delivers great picture quality and truly impressive gaming. I could go on all day long about how smooth each of the games played while testing this monitor, but ultimately not be able to show you without having you sit at the desk with me. No stuttering, no tearing, no lag; it's like getting that new car and having all the sales hype end up being right on the money. When I flip back and forth between my 60Hz monitor and the PC278Q, its like a night and day experience.”

Currently available for a mere $870 the 8GB DDR3-3100 dual channel kit from ADATA with timings of 12-14-14-36 has to be among the most expensive consumer RAM available on the market. We can only hope that DDR4 does not arrive at a similar speed and price point but instead with slower clocked DIMMs at a more reasonable price and with improvements to performance. Legit Reviews' testing showed that these DIMMs offer almost no benefit over DDR3-1600 with tighter timings in real usage but you can get higher scores on synthetic benchmarks. If benchmarking better than the competition and swap-able heatspreaders with different colours is attractive to you then you could pick up these DIMMs, otherwise you really won't be getting value for your money.
"Gone are the days of being on the cutting edge of memory with DDR3 running at 2133MHz! These days running 2133MHz memory is pretty much considered the norm for a high end gaming rig. If you’re looking to be on the bleeding edge of memory speeds you’re going to be limited to only one or two kits. Today we have one of the fastest kits available on the market to put through the paces, the ADATA XPG V3 DDR3 3100MHz 8GB memory kit. Read on to see if this big dollar kit is worth nearly a thousand dollars."

Tagged: Intel, haswell, tsx, errata
Transactional Synchronization Extensions, aka TSX, are a backwards compatible set of instructions which first appeared in some Haswell chips as a method to improve concurrency and multi-threadedness with as little work for the programmer as possible. It was intended to improve the scaling of multi-threaded apps running on multi-core processors and has not yet been widely adopted. The adoption has run into another hurdle, in some cases the use of TSX can cause critical software failures and as a result Intel will be disabling the instruction set via new BIOS/UEFI updates which will be pushed out soon. If your software uses the new instruction set and you wish it to continue to do so you should avoid updating your motherboard BIOS/UEFI and ask your users to do the same. You can read more about this bug/errata and other famous problems over at The Tech Report.
"The TSX instructions built into Intel's Haswell CPU cores haven't become widely used by everyday software just yet, but they promise to make certain types of multithreaded applications run much faster than they can today. Some of the savviest software developers are likely building TSX-enabled software right about now."

NVIDIA Reveals 64-bit Denver CPU Core Details, Headed to New Tegra K1 Powered Devices Later This Year
Subject: Processors | August 11, 2014 - 10:06 PM | Tim Verry
Tagged: tegra k1, project denver, nvidia, Denver, ARMv8, arm, Android, 64-bit
During GTC 2014 NVIDIA launched the Tegra K1, a new mobile SoC that contains a powerful Kepler-based GPU. Initial processors (and the resultant design wins such as the Acer Chromebook 13 and Xiaomi Mi Pad) utilized four ARM Cortex-A15 cores for the CPU side of things, but later this year NVIDIA is deploying a variant of the Tegra K1 SoC that switches out the four A15 cores for two custom (NVIDIA developed) Denver CPU cores.
The custom 64-bit Denver CPU cores use a 7-way superscalar design and run a custom instruction set. Denver is a wide but in-order architecture that allows up to seven operations per clock cycle. NVIDIA is using a custom ISA and on-the-fly binary translation to convert ARMv8 instructions to microcode before execution. A software layer and 128MB cache enhance the Dynamic Code Optimization technology by allowing the processor to examine and optimize the ARM code, convert it to the custom instruction set, and further cache the converted microcode of frequently used applications in a cache (which can be bypassed for infrequently processed code). Using the wider execution engine and Dynamic Code Optimization (which is transparent to ARM developers and does not require updated applications), NVIDIA touts the dual Denver core Tegra K1 as being at least as powerful as the quad and octo-core packing competition.
Further, NVIDIA has claimed at at peak throughput (and in specific situations where application code and DCO can take full advantage of the 7-way execution engine) the Denver-based mobile SoC handily outpaces Intel’s Bay Trail, Apple’s A7 Cyclone, and Qualcomm’s Krait 400 CPU cores. In the results of a synthetic benchmark test provided to The Tech Report, the Denver cores were even challenging Intel’s Haswell-based Celeron 2955U processor. Keeping in mind that these are NVIDIA-provided numbers and likely the best results one can expect, Denver is still quite a bit more capable than existing cores. (Note that the Haswell chips would likely pull much farther ahead when presented with applications that cannot be easily executed in-order with limited instruction parallelism).
NVIDIA is ratcheting up mobile CPU performance with its Denver cores, but it is also aiming for an efficient chip and has implemented several power saving tweaks. Beyond the decision to go with an in-order execution engine (with DCO hopefully mostly making up for that), the beefy Denver cores reportedly feature low latency power state transitions (e.g. between active and idle states), power gating, dynamic voltage, and dynamic clock scaling. The company claims that “Denver's performance will rival some mainstream PC-class CPUs at significantly reduced power consumption.” In real terms this should mean that the two Denver cores in place of the quad core A15 design in the Tegra K1 should not result in significantly lower battery life. The two K1 variants are said to be pin compatible such that OEMs and developers can easily bring upgraded models to market with the faster Denver cores.
For those curious, In the Tegra K1, the two Denver cores (clocked at up to 2.5GHz) share a 16-way L2 cache and each have 128KB instruction and 64KB data L1 caches to themselves. The 128MB Dynamic Code Optimization cache is held in system memory.
Denver is the first (custom) 64-bit ARM processor for Android (with Apple’s A7 being the first 64-bit smartphone chip), and NVIDIA is working on supporting the next generation Android OS known as Android L.
The dual Denver core Tegra K1 is coming later this year and I am excited to see how it performs. The current K1 chip already has a powerful fully CUDA compliant Kepler-based GPU which has enabled awesome projects such as computer vision and even prototype self-driving cars. With the new Kepler GPU and Denver CPU pairing, I’m looking forward to seeing how NVIDIA’s latest chip is put to work and the kinds of devices it enables.
Are you excited for the new Tegra K1 SoC with NVIDIA’s first fully custom cores?

Several rowboats worth of snacks, a couple of canoe-fulls of assorted beverages and boatloads of fun were had this weekend in the highly successful 7th Fragging Frogs VLAN; if you missed it there will be another chance some day but you really missed an epic event. There were over 120 Teamspeak connections in a variety of channels and an estimated peak of 78 active participants. Thanks to AMD there is a new game for the Frogs as well as Plants vs. Zombies Garden Warfare was a hit both to the players and to those watching iamApropos' live stream. We also gained some ARMA 2 fans which will not only appear again next VLAN but is also in danger of becoming a frequent activity for some members.
Once again there was quite a bit of valuable hardware and software given away, the list includes:
- AMD Fan Kit (headset, 16 GB USB drive, mouse)
- AMD Gaming Series RAM - 8 GB of 2133 Mhz
- MSI Military Class 4 A88XM-E35 FM2+ motherboard *and* A10-7850K APU
- AMD FX-8350 Processor
- XFX R9 290 Double D graphics card
- Several Plants vs Zombies: Garden Warfare Origin codes
AMD Red Team+

Just over a month ago Lee took a look at Silverstone's Fanless Nightjar PSU, giving it a Gold Award. It has now arrived in [H]ard|OCP's torture chamber so you can see how well it works with a different system. At the lowest load level of 25% of max the efficiency was a mere 89.79% but at 50%, 75% and 100% loads it stayed well above 90% and the temperature difference was 9C between the lowest load and the highest, impressive for a fanless PSU. In the end not only was this the best fanless 500W PSU [H] has tested, it was the overall best 500W PSU they've seen, justifying the high asking price.
"What is more quiet than a computer power supply with a fan? You guessed it, a PSU with no fan. This unit has small footprint builds in mind featuring excellent Platinum efficiency, flexible flat cables, and of course no sound profile to speak of. Does the 520 watt rated SilverStone Nightjar hold up when we put it in the incubator?"

Linux support for AMD's GPUs has not been progressing at the pace many users would like, though it is improving over time but that is not the same with their APUs. Phoronix just tested the A10-7800 and A6-7400K on Ubuntu 14.04 with kernel 3.13 and the latest Catalyst 14.6 Beta. This preview just covers the raw performance, you can expect to see more published in the near future that will cover new features such as the configurable TDP which exists on these chips. The tests show that the new 7800 can keep pace with the previous 7850K and while the A6-7400K is certainly slower it will be able to handle a Linux machine with relatively light duties. You can see the numbers here.
"At the end of July AMD launched new Kaveri APU models: the A10-7800, A8-7600, and A6-7400K. AMD graciously sent over review samples on their A10-7800 and A6-7400K Kaveri APUs, which we've been benchmarking and have some of the initial Linux performance results to share today."

Tagged: amd, seattle, hot chips
AMD has been showing off a reference Seattle-based server at Hot Chips and The Tech Report had an opportunity to see it. Eight 64-bit Cortex-A57 chips are set up in pairs, each pair sharing 1MB of L2 cache while the 8MB of L3 cache is accessible by all eight chips as well as the coprocessors, memory controller, and I/O subsystems. The system can address up to 128GB of DDR3 or DDR4, and you get support fot 8 SATA 6Gbps ports and 8 lanes of PCIe 3.0 to apportion between the slots. There is a secure System Control Processor, a partitioned Cortex-A5 core with its own ROM, RAM, and I/O to control power, boot and configuration control with support for TrustZone as well as a Cryptographic Coprocessor which accelerates all encryption processes as you might well expect. Read on for more information about AMD's unique new take on server technology.
"For some time now, the features of AMD's Seattle server processor have been painted in broad brush strokes. This morning, at the Hot Chips symposium, AMD is filling in most of the missing details. We were treated to an advance briefing last week, where AMD provided previously confidential information about Seattle's cache network, memory controller, I/O features, and coprocessors."

Today Acer unveiled a new Chromebook powered by an NVIDIA Tegra K1 processor. The aptly-named Chromebook 13 is 13-inch thin and light notebook running Google’s Chrome OS with up to 13 hours of battery life and three times the graphical performance of existing Chromebooks using Intel Bay Trail and Samsung Exynos processors.
The Chromebook 13 is 18mm thick and comes in a white plastic fanless chassis that hosts a 13.3” display, full size keyboard, trackpad, and HD webcam. The Chromebook 13 will be available with a 1366x768 or 1920x1080 resolution panel depending on the particular model (more on that below).
Beyond the usual laptop fixtures, external I/O includes two USB 3.0 ports, HDMI video output, a SD card reader, and a combo headphone/mic jack. Acer has placed one USB port on the left side along with the card reader and one USB port next to the HDMI port on the rear of the laptop. Personally, I welcome the HDMI port placement as it means connecting a second display will not result in a cable invading the mousing area should i wish to use a mouse (and it’s even south paw friendly Scott!).
The Chromebook 13 looks decent from the outside, but it is the internals where the device gets really interesting. Instead of going with an Intel Bay Trail (or even Celeron/Core i3), Acer has opted to team up with NVIDIA to deliver the world’s first NVIDIA-powered Chromebook.
Specifically, the Chromebook 13 uses a NVIDIA Tegra K1 SoC, up to 4GB RAM, and up to 32GB of flash storage. The K1 offers up four A15 CPU cores clocked at 2.1GHz, and a graphics unit with 192 Kepler-based CUDA cores. Acer rates the Chromebook 13 at 11 hours with the 1080p panel or 13 hours when equipped with the 1366x768 resolution display. Even being conservative, the Chromebook 13 looks to be the new leader in Chromebook battery life (with the previous leader claiming 11 hours).
A graph comparing WebGL performance between the NVIDIA Tegra K1, Intel (Bay Trail) Celeron N2830, Samsung Exynos 5800, and Samsung Exynos 5250. Results courtesy NVIDIA.
The Tegra K1 is a powerful little chip, and it is nice to see NVIDIA get a design win here. NVIDIA claims that the Tegra K1, which is rated at 326 GFLOPS of compute performance, offers up to three times the graphics performance of the Bay Trail N2830 and Exynos 5800 SoCs. Additionally, the K1 reportedly uses slightly less power and delivers higher multi-tasking performance. I’m looking forward to seeing independent reviews in this laptop formfactor and hoping that the chip lives up to its promises.
The Chromebook 13 is currently up for pre-order and will be available in September starting at $279. The Tegra K1-powered laptop will hit the United States and Europe first, with other countries to follow. Initially, the Europe roll-out will include “UK, Netherlands, Belgium, Denmark, Sweden, Finland, Norway, France, Germany, Russia, Italy, Spain, South Africa and Switzerland.”
Acer is offering three consumer SKUs and one education SKU that will be exclusively offering through a re-seller. Please see the chart below for the specifications and pricing.
|Acer Chromebook 13 Models||System Memory (RAM)||Storage (flash)||Display||Price MSRP|
|CB5-311-T9B0||2GB||16GB||1920 x 1080||$299.99|
|CB5-311-T1UU||4GB||32GB||1920 x 1080||$379.99|
|CB5-311-T7NN - Base Model||2GB||16GB||1366 x 768||$279.99|
|Educational SKU (Reseller Only)||4GB||16GB||1366 x 768||$329.99|
Intel made some waves in the Chromebook market earlier this year with the announcement of several new Intel-powered Chrome devices and the addition of conflict-free Haswell Core i3 options. It seems that it is now time for the ARM(ed) response. I’m interested to see how NVIDIA’s newest model chip stacks up to the current and upcoming Intel x86 competition in terms of graphics power and battery usage.
As far as Chromebooks go, if the performance is at the point Acer and NVIDIA claim, this one definitely looks like a decent option considering the price. I think a head-to-head between the ASUS C200 (Bay Trail N2830, 2GB RAM, 16GB eMMC, and 1366x768 display at $249.99 MSRP) and Acer Chromebook 13 would be interesting as the real differentiator (beyond aesthetics) is the underlying SoC. I do wish there was a 4GB/16GB/1080p option in the Chromebook 13 lineup though considering the big price jump to get 4GB RAM (mostly as a result of the doubling of flash) in the $379.99 model at, say, $320 MSRP.

This particular Brix is a lot more powerful than most with an i5-4200H and what they refer to as a GeForce GTX 760 with 6GB of GDDR5. The GTX 760 is not quite the same as the desktop version, with 1344 shaders as opposed to 1152 and a slightly lower clock at 967MHz Boost for the GPU and 1250MHz for the RAM. The storage and RAM are left up to you, with the assumption that an SSD will be installed like it was in The Tech Report's review model. The small system was capable of 1080p gaming at medium to high resolution which is rather impressive considering the heat constraints.

As they are enterprise drives they have rather impressive lifespans, the 800GB is rated at 25 full drives writes/day for the length of the 5 year warranty. They also offer encryption and erasure tools that are superior to enthusiast drives, along with a much higher price tag. The Register also offers information on the new Ultrastar HDDs and a link to the spec sheets but as of yet we do not have any benchmarks.

Tagged: ssd, radeon r7, confusing, amd, 19nm
In a branding move that has no possibility of causing confusion, AMD has announce the name of their new SSD line and it seems that the next Radeon R7 240 you buy might be a GPU or then again it might not be. Brand confusion aside, the drives will use 19nm Toshiba NAND fabbed at SanDisk and are predicted to perform similar to other drives with the same NAND, reads of 550MBps and 530MBps write. However as we well know the key to performance lies in the controller and the number of channels so it will be interesting to see the first benchmarks. As The Inquirer points out this could lead to the release of AMD branded machines, containing AMD made APU, RAM, SSD and discrete GPU.
"The Radeon R7 range consisting of 120GB, 240GB and 480GB flavours and is designed to appeal to the gaming market, putting it in direct competition with Micron's Crucial range which expanded to include the MX100, which premiered earlier this year claiming 89 percent performance improvement over a standard hard drive."

Silicon Motion has announced their SM2256 controller. We caught a glimpse of this new controller on the Flash Memory Summit show floor:
The big deal here is the fact that this controller is a complete drop-in solution that can drive multiple different types of flash, as seen below:
The SM2256 can drive all variants of TLC flash.
The controller itself looks to have decent specs, considering it is meant to drive 1xnm TLC flash. Just under 100k random 4k IOPS. Writes are understandably below the max saturation of SATA 6Gb/sec at 400MB/sec (writing to TLC is tricky!). There is also mention of Silicon Motion's NANDXtend Technology, which claims to add some extra ECC and DSP tech towards the end of increasing the ability to correct for bit errors in the flash (more likely as you venture into 8 bit per cell territory).

Tagged: ssd, phase change memory, PCM, hgst, FMS 2014, FMS
According to an HGST press release, the company will bring an SSD based on phase change memory to the 2014 Flash Memory Summit in Santa Clara, California. They claim that it will actually be at their booth, on the show floor, for two days (August 6th and 7th).
The device, which is not branded, connects via PCIe 2.0 x4. It is designed for speed. It is allegedly capable of 3 million IOPS, with just 1.5 microseconds required for a single access. For comparison, the 800GB Intel SSD DC P3700, recently reviewed by Allyn, had a dominating lead over the competitors that he tested. It was just shy of 250 thousand IOPS. This is, supposedly, about twelve times faster.
While it is based on a different technology than NAND, and thus not directly comparable, the PCM chips are apparently manufactured at 45nm. Regardless, that is significantly larger lithography than competing products. Intel is manufacturing their flash at 20nm, while Samsung managed to use a 30nm process for their recent V-NAND launch.
What does concern me is the capacity per chip. According to the press release, it is 1Gb per chip. That is about two orders of magnitude smaller than what NAND is pushing. That is, also, the only reference to capacity in the entire press release. It makes me wonder how small the total drive capacity will be, especially compared to RAM drives.
Of course, because it does not seem to be a marketed product yet, nothing about pricing or availability. It will almost definitely be aimed at the enterprise market, though (especially given HGST's track record).
*** Update from Allyn ***
I'm hijacking Scott's news post with photos of the actual PCM SSD, from the FMS show floor:
In case you all are wondering, yes, it does in fact work:
One of the advantages of PCM is that it is addressed at smaller sections as compared to typical flash memory. This means you can see ~700k *single sector* random IOPS at QD=1. You can only pull off that sort of figure with extremely low IO latency. They only showed this output at their display, but ramping up QD > 1 should reasonably lead to the 3 million figure claimed in their release.

ASUS Republic of Gamers have just released their first FM2+ board, the Crossblade Ranger which should be available for ~$160 in the next few days, a perfect base for the A10-7800 and A6-7400K which Josh just reviewed. There is a host of features on this board, from an updated SupremeFX 2014 audio system to eliminate interference and adjust impedance to the LANGuard and GameFirst III networking enhancements. KeyBot is also new, it allows you to program macros on any USB keyboard regardless of the capabilities of the keyboard itself. Check out the full release for a breakdown of the features.
Fremont, CA (6th August, 2014) - ASUS Republic of Gamers (ROG) today announced the Crossblade Ranger, the first AMD FM2+ motherboard to carry the revered ROG brand name, packed with game-boosting features for an AMD-based gaming powerhouse that is beyond compare. The Crossblade Ranger’s core benefits include the best gaming networking with Intel Gigabit Ethernet, the best gaming audio from SupremeFX 2014, the best gaming interface with KeyBot and the best gaming performance.
Best gaming networking
The Crossblade Ranger is fitted with state-of-the-art Intel Gigabit Ethernet that delivers better throughput and lower power consumption than competing solutions from other vendors.
The new motherboard’s networking capabilities additionally benefit from ROG-exclusive GameFirst III technology for optimal online gameplay. This advanced network-optimization software assigns top priority to game-data packets, allocating them more bandwidth to ensure the best online-gaming experience and clear, stutter-free online team-chat — all controlled with ROG’s usual intuitive flair.
These features are coupled with LANGuard Ethernet socket technology. LANGuard works by employing advanced filtering components with low impedance capacitors to reduce noise and improve throughput and also includes ESD and surge-protection to prevent damage from lightning strikes and static-electricity discharges.
Best gaming audio
Immersive audio is essential for gaming, so the Crossblade Ranger is engineered with SupremeFX 2014. At its core the SupremeFX 2014 solution uses PCB isolation techniques to minimize electromagnetic interference (EMI) and premium ELNA audio capacitors to provide precise 7.1 channel audio that’s on par with the best soundcards.
SupremeFX 2014 features dedicated hardware for features such as Sonic SenseAmp and Sonic SoundStage. Sonic SenseAmp automatically detects analog-audio front-panel (AAFP) headphone impedance and adjusts the amp gain to provide the best volume control range - taking the guesswork and hassle out of setting gain manually.
Sonic Soundstage is a hardware based solution that features preset audio profiles for a variety of gaming genres. First-person shooter (FPS), racing, combat and sports games presets are available via an onboard hardware switch or via the included (Windows) driver package. The benefit of including an onboard hardware switch is that the Sonic Soundstage presets can be applied without needing a driver – so works with any operating system. For Windows users, the presets are fully customizable via software, allowing one to tailor sound to personal preference.
SupremeFX 2014 also includes additional software features to provide a competitive gaming edge and improve immersion.
Designed for first-person shooters (FPS), Sonic Radar II displays a stealthy overlay that shows what opponents and teammates are up to. Players see the precise direction and origin of in-game sounds such as gunshots, footsteps and call-outs, enabling them to hone enemy-pinpointing skills.
Sonic Studio can be used to create virtual surround modes for stereo headsets, provides EQ controls to tune various parts of the audio spectrum and includes noise reduction algorithms for microphones – this all adds up to make SupremeFX 2014 the complete gaming audio solution.
Best gaming interface
The Crossblade Ranger includes KeyBot, a clever tool that lets users instantly ‘upgrade’ an existing keyboard simply by attaching it to the dedicated USB socket.
Once connected, the KeyBot microprocessor is activated and the user is able to use their current keyboard to control multimedia playback, launch favorite applications or assign macros to specific keys —perfect for automating complicated in-game key sequences without the need for an expensive gaming keyboard.
Best gaming performance and experience
Being an ROG motherboard, the Crossblade Ranger is infused with core ROG DNA.
ROG’s Auto-Tuning technology enables the Crossblade Ranger to unleash the true power of AMD APUs with just few mouse clicks. Thanks to the TPU microprocessor (Turbo Processing Unit), the Auto-Tuning routine applies a CPU overclock without need to enter UEFI - perfect for users that are new to the platform.
For users that prefer manual control, the TPU microprocessor and bundled Turbo-V application allows real-time voltage adjustments within the Windows operating system to simplify the process of overclocking a system. Naturally, the ROG UEFI is also chock-full of overclocking functions that help squeeze every ounce of performance from the AMD FM2+ platform.
To keep things cool and quiet, we’ve included five onboard fan headers – each with PWM (4-pin) or DC (3-pin) control. Extensive fan control options are available within UEFI or the automated Fan Xpert 3 calibration utility. Using either method, anyone can customize fan profiles in order to maximize cooling efficiency and eliminate unnecessary fan noise. The level of control on offer here sets a new standard for the FM2+ platform and completely negates the need for using a dedicated and expensive fan controller.
The Crossblade Ranger is also compatible with the ROG Front Base dual-bay gaming panel. The ROG Front Base enables one-click performance boosting, fan-controls, shielded front audio input/outputs, audio profile selection, volume control and real-time system monitoring to provide everything a gamer needs within a single unit.
AVAILABILITY & PRICING
The ASUS ROG Crossblade Ranger lands with an MSRP of $159.99 and will be available at all major online retailers in August.

The new cooling on the 290X tends to have it at the top of the gaming charts and with the impending release of two new FirePro HPC cards AMD looks to take the productivity title away from the Tesla K40. The higher end S9150 boasts 16GB GDDR5 memory with a 512-bit memory interface, 44 GCN compute units with 64 stream processors each there is a total of 2816 stream processors on board. That equates to 5.07 TFLOPS peak single-precision 2.53 TFLOPS peak double-precision performance with theoretical memory bandwidth of 320GB per second. AMD expects the S9150 to have support for OpenCL 2.0 drivers by the end of the year, which the lower priced and specced S9050 will not though both will support AMD Stream technology and OpenCL 1.2. Check them out at The Register.
"The company's new big gun is the FirePro S9150 card, which maxes out at a blistering 5.07 TFLOPS peak single-precision floating-point performance and 2.53 TFLOPS peak double-precision performance."

Origin, with its On the House program, has been releasing games for free, to promote their distribution platform. This time, they dug deep in the back catalog and pulled out Wing Command 3: Heart of the Tiger. This DOS-era game is the last of the three focused on "The Confederation" versus "The Kilrathi". It was also the first to use "full motion video", headlined by Mark Hamill, rather than animated cutscenes. "On the House" makes it free forever, if you declare your interest before the promotion ends.
It is also available at Good Old Games, for $5.99, but it does go on sale from time to time. At the very least, it is probably worth picking it up on Origin and, if you like it, pick up the DRM-free version at GoG.com for safe archival.
And if you don't like it? Well, you're not out much, are you?
