Core2 Duo problems

I have a Core 2 Duo 6300 with 3 Gig of Ram.

I have had problems with an old windows game (Close Combat V). When I first installed the game (windows XP) the game was unplayable. It ran but certain aspects of the game were uplayably slow. For example a 3 second delay on any mouse actions. I then ran the game in Windows 95 Compatiblilty mode and it worked fine.

After this I had to re-install windows. After the re-install (same windows) it just crashes when I run it in compatibility mode. I have a new game (Theater of War) which will run real slow on the system by default. There is a check box in the game setup which allows you to disable dual processor support. When this is disabled the game runs very fast.

Does anyone know how I can create this setting for a game that doesn't have it?

Any advice on this would be greatly appreciated.

Start the game and then look for the executable in Task Manager. From Task Manager you can set core affinity so that that program only runs on the core you specify.

OK, I set the affinity to only one CPU and it fixed it for a few seonds after I switched into the game and then it went slow again. I opened the task manager again and it was still set to 1 cpu. I switched which CPU it was using and it was still slow.

My system:
Windows XP Home SP2
Intel Core2 Duo E6300
ASUS P5N32-SLI Deluxe
3 x Kingston 1GB PC-2-5300 DDR2 SDRAM
2 x Seagate 300 GB Barracuda 7200.9 SATA II (Striped RAID)
eVGA e-GeForce 7900 GS 256MB PCI-E (NVIDIA GeForce 7900 GS)

That should be everything relavant

I have tried every combination of compatibility mode with one CPU running now luck. This is sooooo frustrating. My first Intel CPU in the last 8 computers and it will be my last.
