BF2 Problem with 7800gtx???

[electric turd]

Hi everyone, I have the following: a64 4000+, 2gigs corsair, audigy 2, and 1 7800gtx on a sli asus board with an antec truepower 550w. Now my problem. When I play BF2 occasionally when i'm around the grass/weeds they flicker like hell, almost like they jump from low detail to high detail and back and forth. Everything else looks great in the game but the whole grass/weed flicker/jumping is really annoying. It seems to do it the most when there are loud explosions around or gun shots. I have tried diff. drivers and I cant make it go away. Any ideas would be much appreciated.
Thanks
Lee

OK, Im not sure if this will work but try it anyways....

go to my documents>Battlefield2>mods>BF2>cache

you will have some folders in there, I cant tell you how many because it varies. delete the contents of the folders, but DO NOT delete the folders themselves.

after you do this it will take a little bit for the map to load the first time you try to play, but thats normal and it will only do it once.

Yep i get that plus the wavey textures on the sandbags in some maps.
i think the clearing cache tip will might help though i didnt try it yet because the issue is random to me.
