Has SLI/Crossfire Micro-Stuttering been fixed?

Hello all,

I've been in the dark about new GPUs and their advancements in technology over the past year. I bought a GTX 670 in July 2012, and investigated buying another one to increase performance through SLI.

However, one issue prevented me from buying a second card: Microstuttering.

I'm sort of a perfectionist, and knew if I encountered microstuttering I would not be able to game with it, and I did not want to risk that on a $500 investment.

However, just getting back into tech news, I read that in August of this year AMD released 13.8 drivers, supposedly eliminating microstutter from their crossfire dual gpu setups, which are known to stutter much more than Nvidia Cards.

Do these 13.8 drivers truly fix complete stutter for crossfire setups? Has Nvidia released a driver that also fixes microstutter for dual SLI setups as well?

I tried googling this issue but did not have much success.

Thanks for any answers!

The Crossfire microstuttering fixes aren't in the release drivers yet, but they are in the beta driver releases. The current 13.11 beta driver release has the fix for single display up to 2560x1600 under Direct3D 10+. Applications running OpenGL or render on more than a single display do not yet have the fix in place.

The good news though is that the brand new Hawaii based R9-290 and R9-290X use a different method of syncing the frames and stitching them together. Synchronization is built in to the hardware itself and seemingly works wonderfully across all configurations; as much is indicated in Tom's Hardware's review of the R9-290X.

Older GPUs will have to either make due with the existing beta drivers or wait for the full range of fixes to be rolled out in the near future.

How about Nvidia? Do they have a solution?

The solution that AMD has implemented in their recent beta driver revisions is very similar to the solution that NVidia implemented a while back. Single display SLI/Crossfire under DirectX applications works fine.

Only AMD has implemented a solution at the hardware level, and only with the brand new R9-290 and R9-290X.

IIRC Nvidia have had a hardware level solution in place for some time now.

SLI works near perfect across the board for all resolutions and direct x versions. Crossfire frame-pacing beta fix only works dx11 titles at resolutions lower than 1440p. crossfire still doesnt work well, despite being supported, in many games. SLI works better for more games, it is a much more refined multi-card solution. I have had both crossfire and sli this year alone, sli is much much better. I wouldnt even consider crossfire ever again, not until there is a confirmed fix for the stuttering/dropped frames and better game support. AMD are doing a lot right now, i dont expect the fixes to come soon, they have too much on their plate. They should have focused on getting their cards to deliver smooth game-play instead of working on retarded side projects like mantle and their new hardware accelerated audio thing, and just fixed what they already have. If they had done that, i would probably have 2 AMD cards in my rig right now.
