hi,
Be careful to change affinity only when you have launch a mission, when you see the small image in the middle of your screen (pilot with red start on helmet).
Before this image , launcher.exe and dcs.exe are on affinity on core 0 and 1.
Its only when the mission is lauched that dcs.exe is on core 0.
Work for me on vista32 bit, i double my fps on many mission.
Sorry for my bad english :smilewink:.
