Make your own backlighting

You have refined taste when it comes to keyboards and have exacting qualifications as to the models you want but have now developed a taste for LED backlighting.  The models you find acceptable don't incorporate LEDs or do so in a way you find distasteful.  There is a solution but it is one that will take a long time to pull off.  MAKE:Blog has linked to a project which will take a lot of soldering and more than a little effort but if you want the coolest Dvorak or Sinclair ZX keyboard on the block it might just be worth it.

"Regardless of the hesitation to recommend this project, the final result is quite nice. The final keyboard layout is a Dvorak simplified keyboard, and the wiring is hidden under the keys."

Optical + Accelerometer

When I met with Logitech while setting up for our Hardware Workshop at Quakecon this year, they wanted to show me a new mouse they were coming out with. Of course I was interested, but to be honest, mice have seemingly gone to a point where I could very rarely tell them apart in terms of performance. Logitech promised me this would be different. The catch? The G402 Hyperion Fury includes not just an optical sensor but an accelerometer and gyro combo.

IMG_9323.JPG

Pretty much all mice today use optical sensors to generate data. The sensors are, basically, taking hundreds or thousands of photos of the surface of your desk or mouse and compare them to each other to measure how far and how fast you have moved your mouse. Your PC then takes that data from the mouse at a USB polling rate, up to 1000 Hz with this mouse, and translates it into mouse movement on your desktop and in games.

There is an issue though - at very high speeds of mouse movement, the optical sensor can fail. It essentially loses track of where it is on the surface and can no longer provide accurate data back to the system. At this point, depending on the design of the mouse and driver, the mouse may just stop sending data all together or just attempt to "guess" for a short period of time. Clearly that's not ideal and means that gamers (or any user for that matter) is getting inaccurate measurements. Boo.

To be quite honest though, that doesn't happen with modern mice at your standard speeds, or even standard "fast" gaming motions. According to Logitech, the optical sensor will start to lose tracking somewhere in the 150-180 IPS, or inches per second. That's quite a lot. More precisely that is 3.8 meters per second or 8.5 miles per hour.

AMD Releases FreeSync Information as a FAQ

Subject: General Tech, Graphics Cards, Displays | July 29, 2014 - 09:02 PM |
Tagged: vesa, nvidia, g-sync, freesync, DisplayPort, amd

Dynamic refresh rates have two main purposes: save power by only forcing the monitor to refresh when a new frame is available, and increase animation smoothness by synchronizing to draw rates (rather than "catching the next bus" at 16.67ms, on the 16.67ms, for 60 Hz monitors). Mobile devices prefer the former, while PC gamers are interested in the latter.

Obviously, the video camera nullifies the effect.

NVIDIA was first to make this public with G-Sync. AMD responded with FreeSync, starting with a proposal that was later ratified by VESA as DisplayPort Adaptive-Sync. AMD, then, took up "Project FreeSync" as an AMD "hardware/software solution" to make use of DisplayPort Adaptive-Sync in a way that benefits PC gamers.

Today's news is that AMD has just released an FAQ which explains the standard much more thoroughly than they have in the past. For instance, it clarifies the distinction between DisplayPort Adaptive-Sync and Project FreeSync. Prior to the FAQ, I thought that FreeSync became DisplayPort Adaptive-Sync, and that was that. Now, it is sounding a bit more proprietary, just built upon an open, VESA standard.

If interested, check out the FAQ at AMD's website.

NVIDIA 340.52 Drivers Are Now Available

Tagged: nvidia, geforce, graphics drivers, shield tablet, shield

Alongside the NVIDIA SHIELD Tablet launch, the company has released their GeForce 340.52 drivers. This version allows compatible devices to use GameStream and it, also, is optimized for Metro: Redux and Final Fantasy XIV (China).

The driver supports GeForce 8-series graphics cards, and later. As a reminder, for GPUs that are not based on the Fermi architecture (or later), 340.xx will be your last driver version. NVIDIA does intend to provided extended support for 340.xx (and earlier) drivers until April 1st, 2016. But, when Fermi, Kepler, and Maxwell move on to 343.xx, Tesla and earlier will not. That said, most of the content of this driver is aimed at Kepler and later. Either way, the driver itself is available for those pre-Fermi cards.

I should also mention that a user of Anandtech's forums noted the removal of Miracast from NVIDIA documentation. NVIDIA has yet to comment, although it is still very short notice, at this point.

HGST Announces 12 Gbps SAS, Enterprise SSDs

Subject: General Tech, Storage | July 29, 2014 - 07:24 PM |

You might remember Allyn say that Samsung's 850 Pro is the closest to total saturation of SATA 6Gbps. The other option that we have seen is the bunch of SSDs that are attached to a PCI Express bus. HGST, formerly Hitachi Global Storage Technologies, has just SAS'd back (that was a terrible pun... which I refuse to apologize for) with a Serial Attached SCSI 12 Gbps model (pdf link). They claim a maximum read throughput of 1100 MB/s, with 64K chunks, and 130,000 IOPS, with 4K random accesses.

HGST-12gb-SSD.jpg

The drives will be based on Intel 20nm enterprise-grade NAND with two bits per memory cell (MLC). Its durability is rated at 25 full driver writes per day for 5 years. Models will range from 100GB, all the way up to 1600GB (1.6TB).

While I am limited to Google Translate, there does not appear to be any price or availability information provided. They are enterprise drives, however, so I expect it to be above typical consumer drives.

Watch_Dogs Patched to Optimize Performance and Fix Bugs

Subject: General Tech | July 29, 2014 - 06:55 PM |
Tagged: ubisoft, watch_dogs, watch dogs, pc gaming

Today, Ubisoft has issued a patch for Watch_Dog that fixes bugs and performance issues. Mainly, it is designed to reduce stuttering with higher levels of texture quality, especially "High Textures". "Ultra Textures" could still have problems for "some players", but Ubisoft suggests that future updates to reduce stutter are in progress.

ubisoft-watch_dogs-pistolpose.jpg

Without knowing much about the internal workings of the patch, I expect that it addresses hiccups when swapping textures. Loading textures into memory can take a significant amount of time, and overhead, but it is necessary if the one you need is not in there. As the size of each individual texture increases, fewer can be stored in the same memory space, leading to more swapping required (especially when it is difficult to tell what a user can see at any given point in time). Ubisoft might have found a more efficient organization (for lack of a better word that I can think of) for textures that allow "High Textures" to stay below their target memory footprint, but not "Ultra Textures", at least not frequently enough to call it fixed.

Of course, I could be entirely wrong.

This patch also addresses bugs with multiple network adapters, crashes, and error messages. According to Ubisoft forums, it is available now. It is not yet on their news blog, though.

Nixeus' MODA Mechanical Keyboard keeps it simple

Tagged: input, Nixeus, MODA, mechanical keyboard, Kailh, brown

Nixeus is not a household name by any means but they could heat up competition in the mechanical keyboard market as a new player using relatively new Kailh Brown switches.  Like many ten-keyless gaming boards it has extra blue key caps to make your board more interesting, gold plated USB connectors, a 1000Hz Poll Rate and 6 Key Roll-over.  The Kailh Brown switches are clones of Cherry MX Brown switches and felt almost the same when Legit Reviews tested them.  The keyboard is similar to many already on the market but should appeal to those who prefer simplicity over media buttons and LEDs.

"Founded in California of 2009, Nixeus is still a bit of a newcomer to the PC hardware industry looking to build up a bigger name in the world of monitors and peripherals. Their aggressively priced 1440p monitors which carry the same LG panels found in the iMac displays have been their mainstay for much of that time, but recently Nixeus is expanding to the PC gaming market including the Moda mechanical keyboard being reviewed here on Legit Reviews. Read on to see how this keyboard performs!"

Oculus Rift Dev Kit 2 is starting to arrive, more pixels and less screen door

Subject: General Tech | July 28, 2014 - 02:37 PM |
Tagged: oculus rift, DK2, oled, kick ass

The two top improvements in the second Oculus rift are aimed to reduce the screen door effect by changing the display to a full 1080p OLED screen and the inclusion of Valve's low persistence of vision feature to reduce the image smearing that DK1 users reported.  There is a brand new way of tracking your heads position in 3D with the DK2, a camera tracks the motion of hidden onboard IR LEDs to track translational movement in addition to the rotational tracking existent on the DK1.  You will need 2 free USB ports and it connects to an HDMI or DVI port on your GPU, wireless video streaming is still a hurdle for many applications let alone the Oculus Rift.  Check out the comments on Slashdot and follow the link for a full preview.

"The hotly anticipated Oculus Rift DK2 has begun arriving at doorsteps. The DK2s enhancements include optical positional tracking and a higher resolution panel, up from 1280×800 to 1920×1080 (1080p) and moved to a pentile-matrix OLED panel for display duties. This means higher levels of resolvable detail and a much reduced screen door effect."
