For the people with a Windows system, and an NVidia (Geforce) graphics card, see this thread for help on performance and / or bug -issues and for some slight driver-end help on crashes (hope it helps), the drivers work fine for me in WinXP SP2, and with my 8800GTS GPU.
Hopefully with older variants of Geforce as well.
