Windows 7: Mouse lag and fps problems related to processor affinity

Mouse lag and fps problems related to processor affinity

I am using an Acer aspire 5739G laptop, attempting to play reasonably taxing games including heroes of newerth and starcraft 2. both of these games fall well within the minimum, however, seemingly due to random chance, sometimes upon startup these games will have terrible fps lag or mouse lag.

if i have mouse lag changing the processor affinity will fix it (using a different processor for the game). if i have fps lag this technique works as well, the problem arises when one processor results in mouse lag and one results in shite fps. I have tried changing the affinity of various other processes that may or may not govern my mouse, and i have tried changing my mouse. I have tried upping the priority on the game but this usually results in various random effects, e.g. a button on my mouse may not work.

Two things that would be useful to know - how to change the processor affinity permanently, and which process governs my mouse (ive tried the drivers, no luck).
