I used to be running sli 660ti's but decided to upgrade to a 780ti and for some reason performance has dropped, i used to get 60 fps, until i discovered this. When running task manager as "always on top" while running the game i get almost 60 fps and almost max GPU usage. Any thoughts on this? Screenshots linked below.

its a known issue, most probably because you have V-Sync enabled and lack of triple buffering, there was a limitation and FPS lock on 30 when V-Sync is on, so you either disable V-Sync or use D3DOverrider to force triple buffering with V-Sync.
