Intel core i7 3930K (6 cores)
32 GB ram
Double GTX 580 cards in SLI
And a PSU powerful enough to make use of the stuff.
The max fps i get in game is 110 but it can drop down below 20 in cities.
In most fights i don't even have 40 FPS.
Running the newest drivers for the GFX, motherboard, hard drive controller etc.
1920x1080 and everything on max.
Doesn't matter if i play on 1280 x 1024 with everything on low, i still get fpsdrops.
Reinstalled the drivers, tried older versions of the gfx drivers.
Turned off SLI, put the game in fullscreen and windowed.
Doesn't really change stuff.
How can i make the game playable?
I would try to force v-sync if I were you.
