Some of the readme:
# Doom3: A performance gain of up to 7% is noticed at lower resolutions as a result of more efficient memory use
# Chronicles of Riddick: A performance gain of up to 10% is noticed as a result of more efficient storage of vertex data
# Halo: A performance gain of up to 20% is noticed as a result of generic driver Z-optimizations
# 3DMark05: A performance gain of up to 5% is noticed as a result of generic driver Z-optimizations
Apparently, it's very minor improvements. At higher resolutions there is no improvement at all. I haven't seen low resolutions (like they mention) tested yet.
