hey there.
i just tried 6.3.0 b2, my fps seemed to be less than usual, i checked it.
-dxlevel 98 -novid -nojoy -nosteamcontroller -noff -softparticlesdefaultoff -reuse

6.3.0 b2 maxperformance
2639 frames 21.963 seconds 120.16 fps ( 8.32 ms/f) 9.607 fps variability
2639 frames 21.925 seconds 120.36 fps ( 8.31 ms/f) 9.644 fps variability
2639 frames 21.969 seconds 120.13 fps ( 8.32 ms/f) 9.226 fps variability
6.2.1 maxperformance
2639 frames 21.342 seconds 123.65 fps ( 8.09 ms/f) 9.039 fps variability
2639 frames 21.164 seconds 124.69 fps ( 8.02 ms/f) 8.989 fps variability
i know it's just 5 fps, but when i play some 12v12 match it drops hard.
i think it's because you enabled cl_new_impact_effects and didn't switch it off in maxperformance preset.
what is the reason of turning it on though? just curious.
