Seriously though what we really need is a good sli profile

Btw, afr and afr2 should produce microstutters by its nature and should be unuseful for newer games, as far as I am informed. The dynamic texturing methods and various effects should make afr amd afr2 obsolete, because it works different and is not really compatible to some graphics featires (e.g. volumetric clouds, dust...).

I think, that this is, why you get the stutters. It could reduce in this mode, if you experiment with switching off some features (which is not intended by you anyways, I think).

Would be interesting to compare generally a performance increase with the same settings, and not switching to higher resolution or more graphic details. Otherwise this sli is like I already mentioned. More fps, but more problems...

I can live with my 50-70 fps average on my unboosted card

yes, we need a good sli profile.
Updating Win7 I solved the stutter problems using a default NVIDIA SLI profile (no AFR on NVinspector).As I've written....no need for other comments.

By default it don't use SLI

.
For me same result with and without SLI for the fps scores but temp of graphic cards is bad with SLI and normal without.

I just ran my test scenario and GPU 2 didn't kick in. only about 32 aircraft and i was getting about 40 fps near terrain from GPU 1, about normal.

Maybe C1 have added their SLI support to show us that there's not much benefit ?? .. hmmmm, depends how you impliment it I think? if GPU 2 did all the terrain stuff, that should show benefits ??? just guessing though.

I think you should wait till nvidia confirm support for CloD.

Here I saw that SLI works and vsynch works on gtx690.

You can see difference in FPS with and w/o SLI.

Thats before and after the patch. At least thats what I got out of it.
SLI works the same on a 690, still need profile.

Since the hotfix I was getting more stutters with Crossfire enabled than before. I spent a lot of time tweaking the system yesterday - wanted to go on line on ATAG but decided to try to solve the issues before attempting playing on line. In the end I spent hours messing about and never got to fly! Damn!

I found that I needed to increase the GPU overdrive to max settings (Catalyst Auto Tune max limits) to improve the performance. Interesting that, before I adjusted the settings, the cards were both kicking in but only using about 30% of capacity. Whereas, before the hotfix they were maxing at about 90%.

Now, they each run at about 60% with no penalty on temperature - they get to 68 degrees and sometimes touch 70. Warm but not too hot.

I have CLoD settings pretty much maxed out so performance demand can be quite extreme. Not absolutely perfect, I still get some annoying microstutters and some shimmering on the horizon but not drastic.

In summary, I guess the hotfix has enabled Crossfire to work properly but I have no yardstick to compare anything and have no experience of SLI on Nvidia cards.

Just thought I would throw that info into the mix.

I think, that you will even get more stutters in sli, because the higher fps draws to fast for textures, which have to be loaded up in the vram. Is the vram full, it hicks up even worse, because he do not have all information available in time.

Interesting to hear from a guy using crossfire/sli with 2 cards with 3gb vram each. I thinks, he would run very smooth in comparison to 2x 580's with only 1,5gb. Would be interesting! A slower card with more vram could beat the 580 setup in running smooth and with sufficient fps.

Anyone here with 2.5 or better 3 gb cards?
