Kairu-running with -dxlevel 81 for a tad extra performance. (this disables weapon shines and the gunmetal skins. This will also change the lighting in game) THIS CAN CAUSE PROBLEMS FOR CERTAIN GPU’S. If you experience crashes change the -dxlevel to 90
It's probably worth mentioning that some people just get better framerates on dx9 with mat_picmip -1. It's definitely worth testing for each individual user rather than completely writing it off and saying "use dx8". Not only that, but different dx9 settings will also change results. Personally it goes like this: dxlevel 95 > dxlevel 81 > dxlevel 90 > dxlevel 98. I couldn't tell you exactly what's different or why, but its at least notable.
Ill look into that, im working on throughtly testing all dx levels running on a set test bench with diffrent gpus to see what gets the most fps and see if theres truely a diffrence. I will update when in home tonight. Thanks for the feedback.
