After verifying my files this is my RTS command line

[rts]
; 0 - not use, 1 - show cursor and not capture, 2 - not show cursor, and capture
mouseUse=2
; 0 - not use, 1 - use if hardware exist
joyUse=1
; 0 - not use, 1 - use if hardware exist
trackIRUse=1

[rts_mouse]
SensitivityX=1.0
SensitivityY=1.0
SensitivityZ=1.0
Invert=0
SwapButtons = 0


This was the previous one

[rts]
; tickLen=30
; ProcessAffinityMask=15
; maxTimerTicksInRealTick=20
; 0 - not use, 1 - show cursor and not capture, 2 - not show cursor, and capture
mouseUse=2
; 0 - not use, 1 - use if hardware exist
joyUse=1
; 0 - not use, 1 - use if hardware exist
trackIRUse=1

[rts_mouse]
SensitivityX=1.0
SensitivityY=1.0
SensitivityZ=1.0
Invert=0
SwapButtons = 0


The strange thing is that the game runs exactly the same with the whole Process affinity mask line missing?

Just having another fly around its the smoke/clouds/particles that kill the FPS, and I am not seeing any FPS improvement whatsoever since the Alpha patch.
