Is Mafia 2 supposed to support crossfire?

post #1 of 10
Thread Starter 
Can't find a post with definitive answer on the subject. Found some old threads that seemed like people were running crossfire for mafia 2 but they have all but died.

Anyway is anyone successfully running crossfire with this game? I have it enabled. Works like a charm for BFBC2 but with Mafia I only get 99% load on GPU2 and nothing on GPU1. Clocks are 1000/1360 on both. Other specs in sig.

Thanks in advance.

Worked for me the last time I played, around 10.5 drivers I believe.
Sure you're running full screen?

Actually I'm not running full screen because I was getting game video lock ups with audio that would loop. Only way I manage to get out of that was hard restarts. Finally went to windowed mode and no more lock ups.

I had the same problem, turns out to fix this you need to turn off your CPU OC because for some reason it messes it up. (Don't ask why I have no clue, but the same thing happened for me in APB.)

But I turned off my OC and it fixed it for me.

I believe CF only works in full screen and if its crashing, its due to the drivers or unstable OC

You need full screen for CFX to work.

Lock ups, start checking stability, I get no lock ups.

OK so I went to full screen and set it to my overclock. Played for a little over an hour perfect. Both GPUs were being used and good frame rate. Then all of a sudden I'm having a shootout and GPU usage goes to 0% on both cards and the game is in "slow motion" with 8fps.

Any ideas?

EDIT: If I hit my steam overlay button, I get 60fps but as soon as I close overlay back to game it drops to 8fps again. Even just the game options allow the 60fps but the second I go back to game its back down to 8 that way as well.

Make sure physx is disabled.

Seems to working flawlessly now. I had physx enabled Turned that off and put it back to full screen and I get utilization of both cards.

@Bobicon: I still have both my OCs for my cpu and gpu on. Working fine.

Thanks for all the help.
