Hi , My quake 4 graphics while playing on ultra mode and high resolution look like pixel sprites. especially the guns and doors.

Force Ambient Light is off and i did the required edits on my Quake4Config.cfg file , but no good result.

What the hell to do guys ?

Are you loading Quake 4 from steam? If so, for some reason, the default graphics settings are really messed up. You should google around for "Quake 4 steam graphics" and that should bring up some good results. I had to edit some config file for it not to look horrible.
