The IMPACT only supports 4 bit per component rgb hardware texturing
with 1 Mb of TRAM, the RE2 typically defaults to 5 bit rgb texturing
with Performer, hence the difference.

If you want to improve your road then either convert the image to a 1
component texture for 8 bit precision, or if you have 4 Mb of TRAM you
can change the internal format to 8 bit per component rgb.
