ProcessAffinityMask - =XIII=Shea - 29.11.2009

hi all i have a intel i7 920,with 8 core,s,i am just wondering what i should have my ProcessAffinityMask at in config? tks

- Davis0079 - 29.11.2009

proccess affinity=15 (this is what I use with a quad, from evrything I've seen this makes it run on proccessor 0,1,2,3.)

as for a 8 core I dont think you will find a setting for that, but four out of eight proccessors is going to smoke this game. I can run the blackdeath track with vert sync at an average of 50 fps with a q6600 and SLI 9500's, so you sould be just fine with affinite 15 also.

PS. I'm taking donations of 2xxgt cards if anyone wants to give me a pair of them.

250GT, 235GT (the 2 xx are the numbers, there are various types of the graph cards) :wink:

According to that, with i7 CPU (upto 8 cores), with processAffinityMask=255 you will get all (8) cores running. Althought I'm pretty sure you won't get any improvement in performance.

Ohh ok, but is the last gpu by Nvidia right now? :lol: On waiting the true new gpu the g300 fermie, wait for benchmark :-?




My pc crash on loading game at 30% after load coop with map ?

ok with 6

- agracier - 30.11.2009

This is certainly going to be a silly question, but how does one determine what the frame rate per second of the game is? Is there an in-game command that can be used or do you need a third-party utility?

tks all - =XIII=Shea - 30.11.2009

tks all 4 your responce and agracier you need a third-party utility :o

Shea,

I posted a big segment on this a few months back.

This is the way the ProcessAffinityMask value works in IL2.

If it is commented out the OS will decide which cores to use. ie All cores.
"IL-2 is not a ,multithread application." True
IL-2 only uses 1 core" False.
so PAF....

=1 - core 0
=2 - core 1
=3 - core 0+1
=4 - core 2
=5 - core 0+2
=6 - core 1+2
=7 - core 0+1+2
=8 - core 3
=9 - core 0 + 3
=10 - core 1 + 3
=11 - core 0 + 2 + 3
=12 - core 2 + 3
=13 - core 0 + 2 + 3
=14 - core 1 + 2 + 3
=15 - core 0 + 1 + 2 + 3

commented out - all cores

If a core is enabled, it does NOT mean that core will be performing 100% while the other cores that are not enabled do nothing.
The enabled core needs an active thread to perform,
The disabled cores will be assigned tasks by the OS if needed.
There is only one way to switch off cores - the power switch - meaning all or nothing lol.

There was an long thread at SimHQ some time back exploring this(end 2005/beginning of 2006).

a '1' bit will enable the core, a '0' bit disables it.
Actual activity of cores can be checked through TaskManager. Keep in mind in general Windows OS runs hundreds of threads at the same time IL-2 runs.

A substantial part of IL-2 is written in Java which can use in excess of 100 threads. (source: Sun Microsystems) Shift-Tab opens the Java console in-game Yep that's where all those white messages come from.

Bitmask: 00000000000000000000000000000000 = Decimal 0
Processor affinity is off, and the load is distributed across all available processors.

Bitmask: 00000000000000000000000000000001 = Decimal 1
Processor 1 selected. The process will only run on processor 1.

Bitmask: 00000000000000000000000000000010 = Decimal 2
Processor 2 selected. The process will only run on processor 2.

Bitmask: 00000000000000000000000000000011 = Decimal 3
Processors 1 & 2 selected. The load is distributed across both processors, effectively the same as setting 0 above for Dual cores.

Because 0 puts the load across all processors and 3 puts the load on processor 1 and 2, they are essentially the same thing for Dual core CPUs.

For Quad core CPUs you can use more values:

Bitmask: 00000000000000000000000000000100 = Decimal 4
Processor 3 selected. The process will only run on processor 3.

Bitmask: 00000000000000000000000000001000 = Decimal 8
Processor 4 selected. The process will only run on processor 4.

And any combo between 0 and 15, for example:

Bitmask: 00000000000000000000000000000101 = Decimal 5
Processor 1 and 3 selected. The load is distributed across processor 1 and 3.

Bitmask: 00000000000000000000000000001111 = Decimal 15
Processor 1, 2, 3, and 4 selected. The load is distributed across all processors, 1, 2, 3, and 4.

Get the picture?



Basically, using a multi core processor in IL-2 has no real performance gain when you're talking about just the game, but........
If you use a multicore processor and assign different programs to each core, you get incredible results.

ie. I use an AMD Phenom 9850 quad core with the following settings.

IL-2 is running on Core 4
TS is running on Core 3
HL is running on Core 2
Windows uses Core 1

This is what processor affinity will do for you. Take the load off of the core that you're using for the game by assigning the game to use a core that isn't normally used. Windows, by default, will always try to use the first core (Core 0).

Hope this helps a bit.

I understand how using the affinitmask will assign cores for Il-2, but how do I get windows assigned to (for instance as in your example) Windows to only use core1? I doubt that is done by changing annything in Il-2's config.ini file ...

RE: To all my AAA pals in this Topic - Fireskull - 30.11.2009

The discussion here is overall very useful.

However, Windows Task Manager reveals to me that IL-2 in my Laptop is running in both my cores all the time, which is what I want. NVIDIA System Monitor confirms this. My process affinity mask is set to =3. Also, Windows Task Manager indicates that the nHancer is directing the CPU to process IL-2 (in 8 prerendered frames) of up to 22 threads. Before I even knew that nHancer exists, I had IL-2 running in the first core only most of the time with 1 to 3 threads.

Now IL-2 is all the time running in both cores with no less than 18 threads and sometimes in the mid 20s of threads. My graphics settings are mostly 16 times the default. Though NVIDIA only allows upto 8x graphics, nHancer overides most factory features to reach upto 16x the default. If you have not used it before this, then I highly recommend using nHancer and referring to Windows Task Manager Resource Monitor to know with certainty what cores and how many threads are being used to process IL-2.

My frame rates very from 20 to 70 FPS. When I reduce the Anti-aliaising, then the minimum is 40 FPS in forward cockpit view and maximum of around 80s to 90s FPS in some views.

The graphics settings are set either to the maximum or twice the factory maximum with nHancer, with very few reduced for performance. Guys, I wish that you could see the results. Take last night online flying for example. My first mission of the night I was with my squadron buddies over the Slovenia Map. Even though I have experienced amazing scenes with my new settings, I was again stunned by the exact realism of the mountain region scene. In that mission, there were no distortions or anomalies, though the FPS did drop to about 20 when the plane was near the mountains and clouds. The next mission was the AAA Normandy Map. The whole time I was once again stunned and breathless with amazement at the realism. All the lines, distances, borders, and color transitions-the whole scene, is like a motion picture or real life!

I sincerely hope that this helps people. I really want others to see the nice improvements and get more enjoyment in IL-2.
