Yes you can ... and it's much more stable than on older XP 32 bits. Plus, and this is the best part, should you be running a multi-core processor on XP 64, you can configure Il-2 to make use of either 1, 2, 3 or 4 of your cores.

There was a topic on this and I saved the settings you need to change to put any or all of the cores to work when playing the game. Here they are.

The work on discovering this is not mine and I forget who did find it. The credit belongs to him. But you may wish to use this anyway. I found it very useful.

"This is the way the ProcessAffinityMask value works in IL2.

Actually, using the ProcessAffinityMask and the numbers 1 thru 15, yes that's 15 separate times, I discovered that IL2-46 modded to 4.09b1m would use what ever number was specified in the conf.ini. Here's how I did it. I ran it in window mode and using AMD's power monitor and task manager I can tell the game to use nearly any combination of cpus.

If ProcessAffinityMask=
;1=core #1,
;2=core #2,
;3=core's 1 & 2
;4=core #3,
;5=core's 1 & 3
;6=core's 2 & 3
;7=ALL core's
;8=core #4,
;9=core's #1 3 & 4
;10=core's 2, 3 & 4
;11= core's #1, 2 & 4
;12=core's 3 & 4,
;14= core's 2, 3, &4
;15 or 0=ALL 4 core's
