Hello.

Anyone else having Crossfire problems with 2 HD6750s, 6770s, 5750s or 5770s?

I'm using the stable 12.1 Catalyst driver but the scaling is really weird. And both my GPU's are under utilized.(Both cards only 40-50%)

Ive already tried applying a different crossfire mode (Optimize 1x1) but without Success. AFR mode will introduce more flickering everywhere. (Especially UI items)

ULPS is off, both cards run at the exact same clockspeeds.

FlipQueueSize makes no real effect, tried 5, 4, 3, 2, even totally disabling it.

Can any developer help me? There seems to be no crossfire profiles for this game either.

Edit: alright, got the gpu usage on both cards up to 70% utilization but its still not where its supposed to be.

Alright. I got the scaling to work properly now. Game works great in terms of FPS, both GPUs are almost always above 90%.

The issue is, for this to happen I had to use a different method called AFR or 'Alternate Frame Rendering'.

The issue (as with many games) is the shadows are flickering now. disabling them will stop it but its pretty annoyinng. Some UI things also flicker but thats not nearly as irritating.

Are we ever going to see a proper Crossfire profile for this game?
