ummm....so, without delving into the binary options,
who can tell me the correct setting to use both my cores on my Athlon 5200+ dual-core?

Hi Greybeard,

Thanks for testing, as I said I can't confirm as tracks not running on my install. Did you check in Resource monitor that there is activity on three cores with =84?

I tend to agree with you that this is not going to unlock IL2 for super performance, but I had been getting freezes and some stuttering when only one core is loaded and these seem to be gone when activity is shown on three.

The main point from me is that all the guides on ProcessAffinitymask settings only go up to 15 and none of the settings 0-15 showed activity on more than two cores on my system

Regards,

M

Hi Malone, well as Mike says you need to know if you have hyperthreading (i.e. two real and two virtual cores)

If you have hyperthreading on a dual core:

binary 0101 = 4+1 = 5 in your conf.ini

if you don't have hyperthreading:

binary 11 = 2+1 = 3 in your conf.ini, which by the way agrees with the standard documentation on this feature

And test with resource monitor or similar

Regards,

m

ok, thanks mate - i have tried those settings to see if i can get rid of a micro-stutter that keeps ocurring every 5 seconds or so.
so far, no difference that i can see....

I tend to agree with you that this is not going to unlock IL2 for super performance, but I had been getting freezes and some stuttering when only one core is loaded and these seem to be gone when activity is shown on three.

Computers are like persons: there aren't two identical or, like said a collegue of mine, they're built according a "Babel tower" standard. 

So, if you get improvements with that setting, just use it!

I would only add that, from what I learned in this same forum, game-freezing and stuttering issues can be also depending on available memory: just use the max your system allows (I mean by those special Ivan's il2fb.exe in a modded game or by SAS ModAct)! I tested that my old crappy single-core, 2GB RAM could deal with 768 MB exe, while now (i7, 8GB RAM) I've installed the 2GB exe and furtherlly modded it by that patch which makes 4GB RAM available for IL2, when running a 64 bit Win 7.

Thanks Greybeard, I forgot about using the modified .exe's since Up3 days. I was running the standard HSFX one patched with 4gb patcher but now running the 4gb 6dof one and again without being able to benchmark I think I got a few more FPS (40+ over heavy ground smokes, was 30 something)

Hm , but how come that on the internet some say settings like "3" are most recommended then  some say "1" is the only one working all other the game don't support - at this point I'm even  playing with "15" which someone says it's best for 4-core AMD (or "8"). That is kinda tricky too,right... ??? What is the best then? But gonna try "21" now too...

[marcost]

Hans I've only learnt about this in the last 24 hours but I think the original list 0 to 15 works for up to 4 cores if they don't have hyperthreading (a second 'virtual' core for each real one).

If you have 4 cores and hyperthreading i.e. 8 cores then apply Mike's binary calculation to force the cores you want to use.

Win XP and an AMD Athlon II X4 Quad with 2.8 or so GHz and usually either apply "8" or "15" where 15 seems to be better.

BUT: Tried 28, and 84 today and could swear things ran considerably smoother with both, especially with 84 (?). Tried with the WIP soon to be released Russian master blaster at super sonic and hazy weather in Benghalli and unless I flew over shallow corals, all very smooth and fast...which is rather surprising.

Need to try it in HistoMod with Freddy's Sabre, then I know for sure. That pit eats FPS..

I didn't notice much difference, except for PAM=3 was a little better. Otherwise all is about the same.

In order to make life easier for all of us I made some little tool which calculates the ProcessAffinityMask setting for you, see here:
https://www.sas1946.com/main/index.php/topic,32520.0.html

Hope that helps.

there some stuff in this thread i did about 3 years ago re hyperthreading mainly on page 2,

http://forums.ubi.com/showthread.php/551254-wish-you-could-unlock-the-power?highlight=hyperthreading

i came to the conclusion that i didn't notice any difference in il2 if i recall.
