AMD Catalyst 14.6 Beta Driver Now Available, Adds Mixed Resolution Eyefinity

Subject: General Tech, Graphics Cards | May 27, 2014 - 12:00 AM |
Tagged: radeon, R9, R7, eyefinity, amd

AMD has just launched their Catalyst 14.6 Beta drivers for Windows and Linux. This driver will contain performance improvements for Watch Dogs, launching today in North America, and Murdered: Soul Suspect, which arrives next week. On Linux, the driver now supports Ubuntu 14.04 and its installation process has been upgraded for simplicity and user experience.

Unless performance improvements are more important to you, the biggest feature is the support for Eyefinity with mixed resolutions. With Catalyst 14.6, you no longer need a grid of identical monitors. One example use case, suggested by AMD, is a gamer who purchases an ultra-wide 2560x1080 monitor. They will be able to add a pair of 1080p monitors on either side to create a 6400x1080 viewing surface.

If the monitors are very mismatched, the driver will allow users to letterbox to the largest rectangle contained by every monitor, or "expand" to draw the largest possible rectangle (which will lead to some assets drawing outside of any monitor). A third mode, fill, behaves like Eyefinity currently does. I must give AMD a lot of credit for leaving the choice to the user.

Returning to performance with actual figures, AMD claims "up to" 25% increases in Watch Dogs at 1080p or 28% at 1600p, compared to the previous version. The new CrossFire profile also claims up to 99% scaling in that game, at 2560x1600 with 8x MSAA. Murdered: Soul Suspect will see "up to" 16% improvements on a single card, and "up to" 93% scaling. Each of these results were provided by AMD, which tested on Radeon R9 290X cards. If these CrossFire profiles (well, first, are indicative of actual performance, and) see 99% scaling across two cards, that is pretty remarkable.

A brief mention, AMD has also expanded their JPEG decoder to Kabini. Previously, it was available to Kaveri, as of Catalyst 14.1. This allows using the GPU to display images, with their test showing a series of images being processed in about half of the time. While not claimed by AMD, I expect that the GPU will also be more power-efficient (as the processor can go back to its idle state much quicker, despite activitating another component to do so). Ironically, the three images I used for this news post are encoded in PNG. You might find that amusing.

AMD Catalyst 14.6 Beta Drivers should be now available at their download site.

AMD Expects Beta Eyefinity Fix in January

Subject: General Tech, Graphics Cards | December 11, 2013 - 05:58 PM |
Tagged: frame pacing, frame rating, amd, southern islands, 4k, eyefinity, crossfire, microstutter

The frame pacing issue has been covered at our website for almost a year now. It stems from the original "microstutter" problem which dates back over a year before we could quantify it. We like to use the term "Frame Rating" to denote the testing methodology we now use for our GPU tests.

AMD fared worse at these tests than NVIDIA (although even they had some problems in certain configurations). They have dedicated a lot of man-hours to the problem resulting in a driver updates for certain scenarios. Crossfire while utilizing Eyefinity or 4K MST was one area they did not focus on. The issue has been addressed in Hawaii and AMD asserted that previous cards will get a software fix soon.

The good news is that we have just received word from AMD that they plan on releasing a beta driver for Southern Islands and earlier GPUs (AMD believes it should work for anything that's not "legacy"). As usual, until it ships anything could change, but it looks good for now.

The beta "frame pacing" driver addressing Crossfire with 4K and Eyefinity, for supported HD-series and Southern Islands-based Rx cards, is expected to be public sometime in January.

(Phoronix) Four Monitors on Linux: AMD and NVIDIA

Tagged: linux, nvidia surround, eyefinity

Could four 1080p monitors be 4K on the cheap? Probably not... but keep reading.

Phoronix published an article for users interested in quad monitor gaming on Linux. Sure, you might think this is a bit excessive especially considering the bezel at the center of your screen. On the other hand, imagine you are playing a four player split-screen game. That would definitely get some attention. Each player would be able to tilt their screen out of the view of their opponents while only using a single computer.

In his 8-page editorial, Michael Larabel tests the official and popular open source drivers for both AMD and NVIDIA. The winner was NVIDIA's proprietary driver although the open source solution, Nouveau, seemed to fair the worst of the batch. This is the typical trade-off with NVIDIA. It was only just recent that The Green Giant opened up documentation for the other chefs in the kitchen... so these results may change soon.

If you are interested in gaming on Linux, give the article a read.

Extreme Windows, Extreme Eyefinity, 11,520 x 2160 Gaming

Subject: General Tech, Graphics Cards, Displays | July 25, 2013 - 07:32 PM |
Tagged: eyefinity, crossfire, 4k

Sharp recently sampled a few of their 32" 4K monitors to Microsoft's Extreme Windows. The blog, known for editorializing what enthusiasts can do with Microsoft products, combined three 3840 x 2160 monitors into a 3x1 Eyefinity configuration at 60 Hz; the screen, itself, measures about 7 feet diagonally. This configuration, unlike the already-supported three-display 30 Hz and single-display 60Hz 4K modes, required AMD to develop a customized driver before Sharp's repo-team reclaimed their $15,000 worth of monitors.

They had a day until their door was to be knocked.

4k-eyefinity-01.jpg

The system, three Radeon HD 7970s in Crossfire, successfully drove... they were playing Dirt 3, by the way... the three monitors at 60 Hz with between 62 and 70, of software recorded, FPS. 11,520 x 2160, at 60 Hz, requires 1.5 billion colors to be calculated within a second of animation; that is 1.5 gigapixels. Ignore, for a moment, stutter caused by including Crossfire with an Eyefinity setup. Every calculation, whether properly drawn to the monitor or not is, and must be, performed; 1.5 gigapixels is impressive and an accomplishment for Radeon hardware.

4k-eyefinity-02.jpg

Lastly, I need to call out drama as I see it: power supplies. It is not hard to find a PSU which can support a three-GPU system and no reason for it to be hanging outside the case. It might give off the bleeding-edge appearance, but this is not arc welding. If they really were concerned, they could have picked up a higher capacity device from the shelf of a local component reseller.

3 displays, 1 GPU

If you are going to set up a multimonitor display at 5760x1200 or 5040x1050, but only have a single GPU or a pair of low powered ones, just what kind of performance can you expect?  That is the question Techgage wanted to answer and to that purpose they tested frame rates at those resolutions with NVIDIA's GTX680 and two different 660 Ti's in SLI as well as an HD7970 and two different 7850s in Crossfire.  As you might expect the game tested makes a lot of difference in the results, with many seeing the SLI'd 660 Ti's in the lead while other memory hungry games preferred the large cache of the Radeons.  Check out the individual results of your favourite games in the full article.

"Considering next-gen cards are still months away, we didn't expect to bring any more GPU reviews until the second quarter of 2013. However, we realized there was a gap in our current-gen coverage: triple-monitor gaming. In fact, it's been almost two years since we last stress tested games at resolutions of up to 7680x1600.

We're going to mix things up a little this time. Instead of using each camp's ultra-pricey dual-GPU card (or the new $999 Titan), we're going to see how more affordable Crossfire and SLI setups handle triple-monitor gaming compared to today's single-GPU flagships."

Multimonitor, multidimensional gaming

Subject: General Tech | January 25, 2012 - 05:16 PM |
Tagged: gaming, eyefinity, nvidia surround, 3d display

The Tech Report tackles multi-monitor gaming in 3D with their latest technique of measuring graphical performance.  Frame time seems to be very much present with some hardware when you attempt to play with this type of display but it seems the overall effect on your enjoyment is variable.  When testing Deus Ex they found less instances of high frame time than with Battlefield 3 but found they noticed the impact more on Deus Ex than BF3.  There are a lot of variables to account for in this overview, not only the differences between AMD and NVIDIA's implementation of the technology but also the differences between active shutter and passive glasses.  Read on to see if you should wait for Microsoft to include 3D support in DirectX or if you can dive in right away.
