I picked this up on the CDKeys sale since multi-gpu support was in. At first the game ran amazingly well, holding 120-200 fps on ultra. But if I play long enough my vram usage keeps going up and up, and it stops loading textures properly. I end up with PS2 graphics, doesn't seem to change no matter what I do with settings. I tried running at medium and it still happens, the game looks like dog shit.
I tried reinstalling, and turning off my overclocks. Running the latest driver because it said it was optimized for gears 4 SLI...gonna try rolling back, I guess.

update: rolled back drivers and it seemed to help a bit, but eventually vram usage creeped back up. Disabling 'tiled resources' was another recommendation I saw, but I still eventually need to restart the game to fix this.
For example, I just had to stop playing because vram usage hit 5.5GB and the game turned into a slideshow. Restarted, and it's now using 2.2GB and running 120fps at ultra.
