Been there done that... It happened a lot on my ATI radeon mobility 7500 on my laptop. It made me able to see though walls. This happened back in the first year of ren. Back when the only cheat was lag killing which i used alot. XD too bad my modem has some how turned into a 28k which makes gaming almost not posible. But thanks to UT2k4 i dont need the internet any more.
