Well, to be honest: the game doesn't really run smooth enough to seriously play it. Even on my tibook it is somehow not really smooth. Compared to my pc, there is still a huge difference (at least, when I compare the demos). I was actually pretty good at this game (actually Ut2003) and knew a lot of special moves, such as jump to certain walls in a special angle and strafe jump so you make some kind of superjump. However, such moves became slightly impossible on my tibook
