Hi allHere is an optimization for TrackIR users with dual core who want a few more FPS (TrackIR sucks about 3-5FPS on my system).I noticed that FSX runs mostly on core 0 - core 1 was lightly loaded. So I switched TrackIR's afinity to only core 1, and I got all the FPS which TrackIR was using back - as if it were not running! Greato, TrackIR with no performance penalty.To switch affinity: CTRL-ALT-DEL, click on the processes tab, right click on trackir.exe on the list, the 'set cpu affinity', and then toggle the checkboxes so that only CPU1 is selected.I know FSX isnt great on doing multi-core on its own, but by spreading the cpu load around yourself, you can still get dual core advantage (this trick should help for most apps, not just TrackIR, of course).

I don't use TrackIR myself, however, I tried moving the affinity around for my anti-virus, etc. to leave one full core for FSX and it did help a bit. Thanks for the heads up (I'm new to dual-core myself, still trying to get optimized:P ):-)

Thanks a lot for the tip. Just wondering, where do you see what core FSX is running on?Thanks,Howard
