minimal.exe 
320x240x16
texture filtering = GL_NEAREST
Perspective Hint  = GL_FASTEST
Boolean Fog       = FALSE
this version works "smooth" without 3d card

original.exe 
320x240x32
texture filtering = GL_LINEAR
Perspective Hint  = GL_NICEST
Boolean Fog       = TRUE
not so smooth.

minimal.exe 
640x480x32
texture filtering = GL_LINEAR
Perspective Hint  = GL_NICEST
Boolean Fog       = TRUE
the pain, the PAIN!.
