By the way, anyone who has anything like the system below will be able to play it at 800x600 at low-medium quality.
I took it round my mates house to show him tonight and it ran fine.
Athlon 2100
512MB DDR
Radeon 9600 Pro
Even in medium quality it looks
awesome and AFAIK the only major difference between medium and high quality is the usage of 8xAF.
