I have a EVGA GTX 660 TI 2GB 16X PCIE. On directx 11 or the game is set on directx 11 it runs slow in frames and kinda laggy, even at [low 35fps] and [high 30fps] settings. BUT! when I switch it too "directx 9" it runs perfect like it should, even at ultra settings.
Games I have tried Frycry3, Hitman absolution, Saint row 3, Deus ex revolution. The one game that didnt do it was sleeping dogs.
I had this problem ever since my pc was built, I'd tried reinstalling the graphic card drivers and switching in game settings.
