ArmA 2 is using only 1 of 4 CPU-Cores

[Mr_Tea 0]

Since the Demo ArmA 2 always worked on all 4 Cores of my Phenom 2 X4.

After i installed everything on an new 500 GB HD i was wondering why ArmA 2 performed so bad, and had to find out that it only runs on one of my four CPU-Cores.

"-cpucount=4" is not working, the setting in the ArmA 2 launcher that does the same also has no function.

There are no drivers for the Phenom 2 X4 that i could have forgotten to install, and i have no clue whats wrong now.

I use Vista Home Premium 32 BIT and ArmA is patched to 1.05 off course.

On my Q6600 arma is using all 4 cores. Cpucount enabled in arma 2 launcher.

It seems i found a fix.

With the tool CPU Control i made a rule to bound the ArmA2.exe to all CPU-Cores, now it`s working again.

But i still have no clue why it wan`t work otherwise, even with CPU Control unloaded ArmA 2 refuses to use all cores.

Anyways, it`s working, it`s working.:bounce3:

Did you see a big difference from 1 core vs 4?

Let me quote Mr Tea's opening post:

Well, it's only a really wild guess but to me it sounds like he noticed a slight difference.
