ATI xfire disabling itself?

[wilburnator]

I had similar issues with the last beta patch. I am running dual 6970s on 3 monitors, and would sometimes get blazing performance (60 to 90 fps at 5176x1050) on mostly high settings. I could fly the same mission immediately after and it would be running in the mid 20s to mid 30s at best. I could find no pattern, sometimes it worked great, other times only barely playable.

The good news is, with the current official patch,it is finally consistent... it always runs poorly.

The only way I have been able to get crossfire and fullscreen to give me any more than 20FPS is to use radeon pro to override the driver settings.
When I use radeon pro I get 100FPS to 250FPS on single player and multiplayer.
I dont seem to get any degradation, but MP will crash or kick me out after about an hour without fail.

If I dont use radeon pro its unusable for me with a max of 20FPS even though all GPUs are being used 30-40%. So theres a big issues with crossfire in the last patch that hopefully the beta patch today will fix.
