I’ve checked cpu logs and only my first cpu core being used, and also the multicore rendering option is blank.
Running i5 3570k @ 4.2GHz
GTX 670 OC
306.23 (latest drivers)
DX9 and 11 installed.
Also HDR and Glow effects makes the game extremely choppy, around 20-30fps when HDR is enabled.
I really doubt it’s my system not being able to handle the game.
