GTX 690 tried SLI on and off, 16gb of ram with FX8150 and this game is pretty much not playable, you have most setting using the CPU so basically im running your game on a $1600 paper weight. Multiplayer frames run between 09-24 and mainly stick around 19fps and when i change settings from ultra to low there is little to no difference at all +3-5fps, My card runs at 14% each in SLI and 20% with SLI off. Its a bit hard to alpha test when depression kicks in with these frames.
