Have you checked you IRQ settings? Is the IRQ of youre video card not shared with an other device? If so, turn ACPI in youre BIOS off, and remove it from youre windows. Helped me when running in Win2000. In Win XP no problems though with ACPI.
30 players huh? thats more like it. Ive been reading here for a while and i saw al this crap about 10 to 20 players wich sucks on those big maps. Especialy when youre able to use tanks and helicopters etc etc.
If this is really true what you say, i am happy
