hi,

m8 has a dual rocessor (x3800) and as found that the only way he can handle games like battlefield2 is to run it on one processor, at the mo he reckons he has to make this change everytime the games starts.

any suggestions as to ways around it ?


thx
 
sorry guys, thats what i meant when it has to set it every time he runs the game, from what hes said it doesnt seem to hold the setting, wondered if there was any way around it.

you can set the processor affinity to specific applications...

Download imagecfg.exe utility

then in a command prompt
Code:
imagecfg -a 0xn <Drive:>\Path\yourprogram.exe

where 0xn is the affinity mask. The mask constrains your application to a specific CPU, from 0 - 31, where:

 CPU   MASK
  0    0x1
  1    0x2
  2    0x4
  3    0x8
  4    0x10
 
This thread could help me a bit actually :)

At the moment BF2 obviously only runs at 50% CPU usage due to HT. Is there any way to span it across the two virtual cores? If I can use the program above, what command would I run? (It seems you can only set it to one or the other core at the moment!)

Thanks,

Craig
