Q: What are the system requirements for the game?
A: As fast a machine with the best video card possible. You will want at least a high end P4 3 ghz or the equivalent. I'll be posting some benchmarks, soon.
The game does run on my old Athlon 2700+ with various recent Nvidia cards, with a lowest framerate in the 20-30 range. Some people consider that acceptable, but I am not one of them.
Interestingly, the game does not use a ton of ram. About 180 MB on my high end machine, and until recently the same on my old one. I crossed some kind of threshold recently and suddenly the old machine is using half a gig. Texture memory? I'm really not sure. But a gig of RAM should be plenty.
My development philosophy is to use the power we are given, and to develop on the high end, since by the time the thing is done that should be the new mid-range. I DO NOT try to develop for low end hardware--it's just not my thing at the moment.
