I'm not sure how many people have had to deal with this, but many older games will not run properly on dual core processors. The only way to fix the problem is to bring up the task manager, right click the process, and manually set the affinity to Core 0. Does anyone know a way to permanently set the affinity of a program so it only runs on one core every time you start it? I'm so sick of constantly bringing up the task manager for this issue.

I've found a few lame programs that can set the affinity for you, but then you have to start that program, and run the game through that program which basically adds enough steps so as to completely negate any advantage it might have. If one of those program would run at startup and just sit in the background and do their thing it would be nice, but I can't find any like that.

Yes, I use:

Will set/reset the affinity mask of an executable.

Awesome McFly. Thanks a lot for the help. It works perfectly.

Happy to help + glad it worked.

I'm trying to do this and still having an issue. I followed the directions on the site but it still says

IMAGECFG: unable to map and load C:\Program Files\Zune\Zune.exe

The command I'm using is this.

imagecfg -a 0x1 "%programfiles%\zune\zune.exe"

Same result when doing -u {pathname} the line previous.

Hans, have you the MS dual core hotfix installed, and the AMD driver???

There should be no need for permanently setting the affinity is you do.

I had issues with older programs until I installed those properly, then everything was perfect.

Hey thanks for that app Mk Fly.

Way out of topic but whats up with the Latvia nickname? You moved over there or something?

You know, I just went over everything and realized that when I put the registry entry in for the hotfix I had the hexidecimal value set as 0 instead of 1. I think that's why I was having trouble. Now it looks like I won't need that program. Either way, I've learned new things. Thanks.

I've moved back. I'm currently living in a derelict warehouse with a few others.

Cool. I wish I had a derelict warehouse with a 'net connection.

Will you be arriving in Ireland at any stage?

It was once more of a factory than a warehouse I suppose.
