look at what happened when i tried to run the Xterminate terrain engine: Now that''s fun The effect is even higher and lower than on the picture, but I couldn''t get the screenshot at the right time. Last time when I ran it, it was fine (I had a different video card then). Now I have a PowerColor GF2 MX. I''ve noticed a similar effect on some other things. (Like my octree tutorial demo in windows, for example. In linux the same code runs just fine but in Windows everything is kinda off.) gotta update my drivers This post wasn''t ment to be a blab on how sucky my system is, but just to show that pic --- cone3d http://cone3d.gz.ee -> soon http://cone3d.gamedev.net
