I have 10.11 drivers installed with my 4850's CFX setup, and when I play Call of Duty: Black Ops it stutters and I get horrible FPS. I tried lowering the resolution, that didnt help one bit. Then I tried disabling Crossfire and that fixed it. It runs fine, but then I had to turn down the graphics since one 4850 couldnt handle everything turned up at 1920x1080. This really sucks, should I just buy the new 6870's?
PII X3 720BE @3.0GHz
4GB DDR2 800MHz
XFX 4850's in CFX
1TB 7200 RPM HD
i have steam installed, it updated the game when i installed it. Its never run right since its been installed. both cards are seated correctly, when i disable CFX i do it through CCC. I dont physically take out the cards or anything. ANd it doesnt do this in any other game. MoH 2010 plays great and smooth, what i find weird is I used to get 120-140 FPS in MW2 then after installing 10.11 it does the same thing in MW2 that it does in Black Ops, but when i disable CFX MW2 doesnt get better. I installed older drivers but that didnt do anything at all. It may be a bad card, ive seen other reviews where people with the same cards as mine arent having any problems with CFX.
Im thinking about building a new system anyway. Just let me know what yall think about the situation.
Are you running windows 7 64 bit? I have the same problem as you. Before, when I had win xp I had crossfire enabled and had great performance with MW2, then after I installed win 7 64 bit having crossfire ruined my performance on MW2. I didn't realize it was the crossfire issue until exhausting all options (multiple reinstalls of win7, tons of driver updates, I even went into sound settings). Still don't have a fix, so i'm forced to run just one card and have the other one sitting there collecting dust.
i took out my cards cleaned the dust off them, tested them independently and put both back in after nothing was wrong. Now crossfire works fine in Black Ops, but i still have bad FPS. Now it freezes up and crashes when CFX is enabled, but not when CFX is disabled.
@ OP all i have to say..black ops blows big chunks just visit black ops forum,there was/is so many problems with this game it's ridiculous,had my system crashing once by puling headset from USB port,CF is another issue,try runing single card
