I correctly installed Red Alert on my laptop with vista on it. And for some reason about 5 minutes into any game I starts to slow down severly. I mean If I build something and move forces at the same time it about stops.

I have no idea what could be causing this.

RA95 properties set to:
Run in 95 windows....tried 98/me and it made no difference
run in 640X480 resolution
disable visual themes
disable desktop compostion
disable display scaling on high DPI settings

If anyone could help me with this it would be much appreciated!
