Far Cry 2 - FPS drop over time - Ideas? | Forums

[Jason-Alaska]

I have the Steam version of Far Cry 2 and I have a FPS drop after 30-40 minutes of play.

I can run maxed at 1920x1200 and getting 45-60fps in FRAPS. Then I'll see it drop to 30-40fps a few minutes later... Then 20-30 a few minutes after that. Until finally it settles in at 17-24fps.

I have tried it in SLI and Non-SLI and have the same issue but with lower FPS in non-sli.

When I have this issue, I ALT-TAB out and close some background apps. I don't know why this works IN GAME because it does not work if I close the background apps before launching the game.

I'll ALT-TAB and close Itunes, the Apple helper app and anything else that looks like it's not needed. This will fix it for me for another 30-40 minutes. At which time it will start to have the FPS drop again. Only fix then is a restart of the game. (Shrug)

Any suggestions on a fix or workaround? It sure seems like a memory leak in game but I'm surprised other have not reported the issue here.

Windows Vista Ultimate 32 SP1

whats the GPU temps when playing and FPS drop? 8800s are old cards and have known to be pretty hot cards.

Great question thafuriousone,
I had ignored that possibility as every other app from Photoshop CS4 to Fallout3 to HAWX works great.

I'm running some temp tests now.

GPU temps at idle seem kinda high. Ya can use precision from EVGA to monitor temps in game with on screen display or use rivatuner if precision isnt compatable with your cards.
