Blodrast,

About the ATI card thing. You might try increasing the details. I'm using a 9800 Pro and maxed everything in the game (except left off AA) at 1280x960, and clicked the "glint" box. That cleared it up. I've not yet gone back and determined what is causing the orange triangles in the default settings, but I got it for about 2 seconds every time a volley of flaming arrows struck. After I maxed the graphics details the orange triangles disappeared completely.

Great post by the way!
