For what it is worth I have found no advantage in setting processor affinities for IL-2.
With all unnecssary processes shut down (using FSAutostart) I ran the following tests:
No Processor affinities
Black Death Track
End Results 32.34.75.11 and 35.34.74.12
(run twice, at beginning and end, in case of any caching issues with run #1)
IL-2 only set to core 0 (ProcessorAffinty=1)
Black Death Track
End result 35.33.76.9
IL-2 set to core 0 and everything else possible set to core 1 (I used setaffinty.exe)
Black Death Track
End Result 32.34.74.10
As you can see the results were virtually identical.
Given that the BDT will return results for the same setup varying by 1 or 2 fps I'd say that there's no point in setting affinities, at least not on a dual core processor.
My rig:
ASUS A8N32 deluxe SLi mobo
AMD 64x2 3800+ CPU
2 x XFX 7800GT SLi 256Mb
2Gb Corsair low latency RAM 2-2-2-5
450w PSU
Windows XP SP2
Samsung 226BW 22" Widescreen 1680 x 1050
Saitek X52 HOTAS and Rudders
TrackIR4 and Pro Clip
