I can use my usb adaoter on my PS/2 mouse. Under 98 I could rin with ALL options maxed out. Under XP I still can get a decent looking game but not as nice. 32 color depth, 1024 * 768 res, texture detail max, player detail max, bench med, lighting low, shadows med, reflections low, environment med, v-sync on, buffer antro.
Anyone thinking of upgrading just for this game dont!!! Stay at 98 and dont use usb adapters on non-usb devices.
