I have a new computer and I was asking myself....

The problem with "ProcessAffinityMask=2" is, that IL2 was not built to use multiple cores and therefore it can cause stutters to run IL2 on 2 cores. I rather recommend assigning IL2 to one core, Teamspeak, TrackIR and other programs you need, to the second. That solved a lot of microstutters for me, but you should try that one out yourself, as it probably really depends on the system configuration.
