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?
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.
