I play on several different servers, sometimes, but not always, my computer runs at too many frames per second for the server.  Those that have an FPS limiter (30fps max), i get booted for having high frames per second.  It doesnt do it all the time, just randomely. 
I have an MSI K9N2 SLI Platinum mobo.  AMD 6000+ dual-core processor. and 2 gigs of ram.  MSI 9600GSO vid card. 
Someone said to set the processor affinity to make the application run with only one processor, I have done that and it doesnt seem to help. 
I can make it stop by rebooting the system but eventually it starts running at higher fps again. 
I'm stumped? Anyone?
