AMD Has Announced More New GPUs – the Radeon HD 7850 and 7870

March 5th, 2012 · No Comments · Other S3D Tech


Last few months AMD has been announcing one new graphics processor after another from their new Radeon HD 7000 series, something that is not bad considering that before that we’ve had quite a long time with the last generation. Together with the release of the Radeon HD 7000 series AMD has also brought some new features regarding stereoscopic 3D support and the Radeon HD 7850/7870 essentially brings a bit slow in terms of performance and more affordable in terms of price graphics cards on the table for gamers with more limited budget. Now it is maybe time to for Nvidia to bring out what they have been working on secretly up until now since the announcement of the last generation of graphics processors that they also had quite a while ago.

One of the things that I was eager trying out with the new Radeon HD 7000 series of video cards was the Multi-GPU Crossfire support in stereo 3D mode that the company has introduced, however there are still a few things that are preventing me to do it. First the lack of official drivers for the Radeon HD 7000 series that include proper support for all the new features as AMD has been struggling with that apparently and currently only offer 12.1 WHQL and Catalyst 12.2 Pre-Certified Driver. Second, a good active 3D monitor to use for testing that can properly bring out the full performance from two Radeon HD 7970 cards for example, Samsung’s SA 750/950 series of 3D displays are pretty much the only good option for that, however these are still not available everywhere like in my region for example… we only have the TA series with built-in 3D TV tuner here and no DL-DVI interface. Meanwhile I’ve already tested the Catalyst 12.1 drivers together with my trustworthy old Radeon HD 5970 dual-GPU card working in Crossfire mode on a Passive 3D display from LG and it worked very well in stereo 3D mode, although performance wise it was a bit slow at times, but it is already a bit old GPU. So stay tuned, hopefully sooner than later, for a comparison review of the new AMD Radeon GPUs like the Radeon HD 7970, 7870, 7850 etc. in stereo 3D mode.

Trying the Game Alan Wake in Stereo 3D Mode With 3D Vision

February 17th, 2012 · 15 Comments · Stereo 3D Games


The game Alan Wake is finally available for PC as well, for now only on Steam, but it should make its appearance on Origin and in a retail version shortly. And with the developers of the game talking about the game supporting 3D Vision and AMD HD3D as well as teasing us with multi-monitor setups prior to the release of the game the stereo 3D gamers were eagerly anticipating this release. But now that the game is finally available and many stereoscopic 3D gamers that have tried it report that it is far from perfect in stereo 3D mode with 3D Vision.

So when Remedy Entertainment said that the game:
– Works with AMD Eyefinity 3D 3-screen mode.
– Works with NVIDIA NVISION2 Stereoscopic 3D.

Will Alan Wake PC support Stereoscopic 3D?
We have internally tested that the game works with NVISION 3D very nicely. It is fairly performance heavy though so a high end GPU such as the GeForce 580GTX and moderate graphics settings are recommended.
Remedy has not been able to test AMD HD3D (we spent some time trying), but AMD has access to the build and we are hoping they can confirm whether it works or not.

They probably have meant that the game can run with 3D Vision and AMD HD3D, but they were not referring to the level of quality you can expect to get in stereo 3D mode. The developers actually recommend to play the game with a very low level of depth and indeed when you just have a few bars of depth the issues of the game rendered in stereo 3D mode are not that apparent and it is actually playable. However stereo 3D gamers usually tend to play with high levels of depth and a lot of them also ten do tweak the convergence levels as well. With Alan Wake however you should not try this as it will literally make the game unplayable as increasing depth or messing up with convergence simply makes very apparent the issue with the dynamic shadow rendering that the game has in stereo 3D mode as well as the issue with lights. But saying that a game with such issues works “very nicely” with 3D Vision isn’t acceptable at all and it is very misleading. The game may be playable with very low depth levels, but that is only something that can be called acceptable at best and not “very nicely”… so if you have considered getting the game Alan wake with the idea to play it in stereo 3D mode, you better wait a bit more to see if the issues that the game currently has in stereo 3D mode get resolved first.
