Hi, I have an i5-3210 and have the exact same problem both the dx9 and dx11 .exe only use core 0 and 2 and I have to change it every time I launch the game, in order to play smoothly. I really don't get it.
Also I still get some eventual lag when running DX11 version but since my graphics card isn't that great(HD7670m, is a laptop) dx9 is good enough.
