Yes doomguy u can run that even with higher aa or af

on 1024 768 u wont have a problem with the gameplay but my guess is that u will get some laggy frames when trying to run the game at 1280 1024 or higher bcuz of missing 512 Mb ram and ur xp2000+

my guess is that to run the alpha lagless at those high res u should have 1Gb of ram and xp 2500+ Barton AT LEAST
