Frame Rating: Eyefinity vs Surround

Ryan and his band of merry men over at PC Perspective have published an article titled "Frame Rating: Eyefinity vs Surround in Single and Multi-GPU Configurations" that is certainly worth checking out.

As I mentioned on a previous page, AMD, as they have previously stated, is committed to fixing these CrossFire + Eyefinity problems for the upcoming generation of products and the current Radeon HD 7000-series of cards. Though much of the discussion is still going to be embargoed until further notice I have renewed confidence that the substantial Frame Rating issues with these configurations will be addressed, I just don’t know exactly when. For gamers that have already invested in this ecosystem of multi-display, multi-GPU hardware that answer isn’t going to appease them but it does make this information presented today easier to accept.

I have to give Kudos to PCper for taking the time and effort to demonstrate what Kyle and Co have been saying for Ages.

I've read on numerous times where [H] states that even though Xfire "runs faster" its less fluid than Sli. PCper clearly shows the diffence between Fraps FPS vs Observed FPS. While 7970 Crossfire is clearly faster on FPS , the observed FPS is not much better than single 7970.

I'm not to say AMD is cheating, as Frame metering doesn't decrease performance by much if at all. But they do have to step up and finally give a fully working crossfire solution.

Even with all the pressure PCper is giving AMD they still slow in releasing fixes and in incremental stages. DX9 games still not addressed, it does not address resolutions above 2560x1600, more glitches present themselves in current and old games.
"At the same time, AMD has also committed to addressing these cases in a future update. Details of the rollout for this solution will become very evident, and made public in the very near future."

So that would be somewhere next year maybe? lol

What's worrying is what Ryan mentions in the article about the upcoming new GPU's if this issue will still be present, it's still a software/driver solution and no word on a hardware fix like Nvidia has in place for years.

Nvidia has been working on microstutter for years. This isn't something just fixed with Kepler.

I wouldn't expect for them to completely address this issue overnight. I'm just glad that they're finally addressing it.

I haven't seen any claims of hardware metering on any cards outside of GTX690. Nvidia's microstutter fixes may very well just be software.

I believe that all of the Kepler cards have carried some level of hardware based mitigation.

Link? I've only seen that claim made for the GTX690 and it would explain why GTX690 does better than GTX680 sli in FCAT.

The original launch key note for the GTX690 draws attention to the fact that hardware frame metering is part of the Kepler architecture.

http://www.geforce.com/whats-new/articles/article-keynote

"Kepler introduces hardware based frame rate metering, a technology that helps to minimize stuttering. In SLI mode, two GPUs share the workload by operating on successive frames; one GPU works on the current frame while the other GPU works on the next frame. But because the workload of each frame is different, the two GPUs will complete their frames at different times. Sending the frames to the monitor at varying intervals can result in perceived stuttering."

The slight improvement you get in stutter over 2 card SLI on the 690 is likely the result of the 2 GPU's living on the same PCB and the same set of PCI-E lanes which helps to reduce the latency a little more.
