First, I download small games, this game is only 2D and can only move left and right, but very lag. In windows xp, i can play gta 3 and vice city in full speed, CS 1.6 (medium quality) smoothly, NFS Underground 2 little lag.
So, this is because the OS or because of a game that I downloaded? If I download another game, whether it will lag too?
I have a netbook with Intel Atom N280 and 1GB of RAM.
edit I can play Final Fantasy VII using from software center PCSX smoothly in Ubuntu.
