Hmm, I got my FPS way up! But I still have a really horrible glitch.

Hey guys, I downloaded the 1.9gig crysis demo from fileplanet, and now I get 30 FPS on high again. But I have a really horrible glitch, all of my trees are glowing. Pics!Does anyone know how to fix it? I get that glitch even with all of my settings on very high...[IMG]http://i140.photobucket.com/albums/r22/Spam-Robot/Crysis2007-10-2711-12-57-33.jpg[/IMG]
