Multi Core CPU Tweak for IL2
I got an e-mail from a friend of mine regarding a multi-core CPU fix. Has anyone heard of this for multi-core CPU's:

I've heard, I am using AMD Dual core Optimizer Didn't have any improvement in performance but it sure help for game which have bad problem with dual core
For example run to fast or have LAG's
http://support.microsoft.com/default.as ... spid=11920 This is something similar for VISTA I think
I found it on this site http://www.nvnews.net/vbulletin/showthread.php?t=116865
But b4 you screw your system with this update read what ppl says bout it, not everyone like it.

Do you know about this "processaffinitymask" thing?
go into your conf.in, look for the RTS section. Find:
";processaffinitymask=0"
change it to:
"processaffinitymask=3"

I use ProcessAffinityMask=2 because imho its an advantage if your game got its own core to run on.

Well I have made some comparison.
AMD Dual core 64x2 4000+, Nvidia8500GT, 2048 Ram.
When i make this test i played black death track usually I use this track often to compare performance between different settings i use it so often that i remember where and what FPS I've had.
During this test there was no performance boost at all regardless of core affinity.
I've had as usual 50 FPS at the beginning 28 FPS at second explosion 25 FPS when il2 shoot rackets at plane and building and the lowest FPS 15 when there was moment with friendly fire and collision in the mid air.
Almost forgot Il 2 settings everything maxed out except
"trees=0"
"water=0" its still in perfect mode so its using shaders (means its not so simple as directX)
"Efect=1"
"Landshading=2"(in perfect mode this will leave landshading as it is but will remove shadows from trees and buildings which is mean huge fps boost over palms during attack on pearl harbour and allow you to fly over Berlin very low at decent fps )
"LandGeom=3"(for new dll which improve quality coastlines and visibility distance but cost something about 5 fps damn worth it )


While doing it i played "Black death track" And I Didn't notice any performance improvement.
But notice how high is load on single core when you set affinity to only one core. (image in the middle)
I am pretty sure that this is no good for long time. I mean its quite high load on 1 core only.
I don't know can processor work like this for long period or not. Someone more knowledgeable could take a part in discussion.

For now My advice is turn off Vsync OR force tripple buffer with Vsync.
And this is mandatory for multi cores DISABLE MULTITHREADING
