OpenGL - black screen w/ strange texture glitches

[DanaW]

I can load roms like f zero gx and need for speed most wanted but they are unplayable because of a strange glitch that occurs when I use the open gl setting. I'll boot up the game and the screen will either be a blank background, or a mostly black screen with a few texture popping up from the game. I'm really frustrated and could use some help thanks.

I find Direct3D is better for most games anyway, especially Wii ones.
