I just decided to finally ditch motion blur. At first I liked it but without it the game just feels a bit more smooth, almost like there's a bit of a mouselag effect to motionblur (which effectively feels like a bit of mouselag). I'll save this effect for my DX10 card
Also I upgraded the shadow spec from 2 to 3 (medium to high) as I noticed the shadows kinda jittered and they looked a bit too low res (noticed this when I looked at my own shadow). 3/high seems better and overall from turning the shadows up and disabling motion blur, I got +1½ FPS in the benchmark and went from 22 to 23½.
