I have arund 25-30fps, and worse and input lag of 20-30ms, sometimes higher, and the hole thing feels laggy. Its not so surprising as the cpu is weak, NS2 has troubles as well. But to my surprise new titles like Asssassins Creed 3, Carrier Command: Gaeiea Mission work fine, even if I have to choose low quality, they are perfectly playable.
So I guess DirtyBomb should run also fine? Well we are in alpha - but it would help for the stats, not having them polluted with player having fps/input lag issues.
