I use SFFT Alpha33 + 3dfxTools.My system is below.
1)With Fastest Performance and 2 sample Anti-Aliasing modes:
I set video options by default,800x600 32bit resolution and I got a good image quality but the game is slow.
2)With Single Chip Only (compatibility mode):
I set video options as above and I got the same image quality but the game is more fast.
Thenks for any additional information;)
