Fuzzy screen help

Every time I get on UT3 some maps will only be fuzzy like a snow type of thing an its also in my menu so I cant see anything that well, can some help me get rid of it?

My PC does this to me sometimes, but its completely temporary for me. When I first start a match, all the textures are blurry, crappy, and really hard to look at. But after a few seconds my PC finishes rendering them, and UT3 looks just as good as Quake 4 or Doom 3.

My guess is that ur PC takes a bit to render all the visual stuff, or it might just be a pure issue.

There is a setting in the config files to dissables streaming textures, but the map will take much longer to load.
