Processor Affinity

Good day,

I have an AMD Dual Core 3800+ processor and I play a game called Splinter Cell. In order for me to play it well, I need to set the processor affinity to CPU 0 only. For some reason if both cores work with the game, it lags horribly.

My question is: Is it safe to do this? Doesn't this put a lot of strain on CPU 0 while CPU 1 does absolutely nothing? Can it damage the core?

Thanks,
Slikkie

There is a patch from AMD which may solve this problem which does occur on some gaming systems.

Download the Dual-Core Optimizer patch from http://www.amd.com/u...1_13118,00.html and then fire up both cores again and see if this solves the problem.

The fixes in the first post at http://www.hardforum...ad.php?t=983781 might also be of interest.

Thanks for the link. I downloaded the setup and installed. The game runs much better now with both cores working, but yet I can still get a little bit extra performance if I set the affinity to only one core. Is it at all healthy for the single core to have such a work load for hours at a time?

Makes no difference, or rather dual-core hasn't been out long enough for it to be any of major concern to anybody else.
