runs pretty well apart from on graphical error (as far as i can see..)
Mechwarrior 4: Ultra high detail.. 1024x768x32
runs very well apart from the fact it looks a bit sucky! it has the same problem with lighting. im no expert but im guessing it has to do with the vertex shaders.. you get this repetition of light across the texture.
Im using the latest Evolution drivers, Raziel64 u might be interested to look in to this?
