As someone mentioned, before, the problem with Crossfire on multi-GPU ATI cards and flickering is resolved with the latest 11.3 Catalyst drivers (note, however, that the latest drivers provided via Steam are only 11.2). HOWEVER, can anyone else confirm what I seem to be seeing? That is, that when running Crysis with 11.3, it is only using one GPU?
That's not really a solution. That suggests to me that the driver is using a profile for Crysis that disables one of the GPUs, which is what we already knew we could do manually. The real solution needs to be that it works, without flickering, utilizing the full card(s).
Not sure if you are referring to single multi GPUs ATI cards or multiple single GPU ATI card in CFX setup. In the latter case I should deny that Catalyst 11.3 actually resolve flickering issue, at least for retail version of the game and dual HD5870. In my previous post anyway I explained how combination of CCC 11.3 and 11.2 CAP4 with brightness adjust seemed to drastically reduce flickering problem. And in this case I should deny once more that with 11.3 Crysis is running one GPU beacause I'm actually playing it with both GPUs.
By the way, make sure of checking CFX status in Ati Control Panel after reinstalling drivers before running the game >.>
As of yesterday, the 11.3 Catalyst drivers alleviated the flicker problem in single multi-GPU ATI cards (the HD5970, at least). However, it was only using one GPU. As of today (presumably after a Crysis patch), it shows that it is using both GPUs *and* the flickering remains fixed.
However, the performance -- despite now using both GPUs -- is miserable. I'm getting around 20fps in single player at 1920x1200 on the highest setting. In multiplayer, I'm just sticking around 30fps . . . but only after using the lowest settings and running at 1440x900. It's absolutely miserable.
