Anyways i have tryed another psu (650w corshair with higher ampere on 12v rails. then mine), and 2 psu together and got this result:
Bad Compnay 2. Dx10:
650W Crossfire: Load about 35% Fps = about 100
650W Singel card: Load: about 80% Fps = about 100
1 card on 600w psu and 1 card on 650w psu: CF Load: about 35% Fps = about 95
This test was done on the same map, on the same empty server, and running the same round.
So from what i can see an higher output psu dont seem to help me. It seems as when running crossfire it just puts the load across the 2 cards, instead of pushing a single card. This test was done with 11.2 drivers and profiles, tho i have tested it with 10.11 drivers and profiles, but same result there. It is no increase in peformance with crossfire, just lower loads of the 2 cards. And well i dont seem to find any setting to make the card push the load on both cards either. Kinda running out of ideas on where the problem is.Edited by Concker - 2/20/11 at 6:09am
