OpenGL and Unreal Tournament

Hey guys, hope you can help me out.

I recently switched to OpenGL. WOW oh WOW. My FPS is finaly STABLE. The
image quality seems better. I also copied all the UTX files from the 2nd CD.
All in all it looks good. With the exception of one thing. As some of you
may know I play Giant Maps, we are talking big ass maps. So objects in the
distance I can sometimes see through and thats no fun it makes the map look
really weird and ugly. Not to mention that it distracts and hurts the eyes.
I also get these effects in maps that come with UT original package (for
example in the DM-Barricade map, on top of the tower I can see this
effect).For example in the Giant Bathroom map I look at the pharmacy and
instead of seeing the reflected wall in the mirror, I see the shelves behind
it and some textures seem somewhatweird from afar. Or I will see hidden
features through a wall.

I use a PIII 666Mhz with an annihilator 2 (Geforce2 GTS) video card on an
17’ optiquest Q71 monitor. My UT settings are as follows: 80060032
resolution, textures are at Medium

This is my OpenGL settings in my unrealTournament.INI

[OpenGLDrv.OpenGLRenderDevice]
RefreshRate=75
DetailTextures=1
UseTrilinear=1
UseS3TC=1
UseTNT=0
LODBias=0
UseMultiTexture=1
UsePalette=1
UseAlphaPalette=0
Translucency=1
VolumetricLighting=1
ShinySurfaces=1
Coronas=1
HighDetailActors=1
MaxAnisotropy=0
AlwaysMipmap=0
UsePrecache=1
SupportsLazyTextures=0

I tried GTU and replacing the DLL with newer version. ANY help would be
greatly appreciated.

TIA

Check with nvidia that you have the latest drivers.
