Notes:
- Performance should be improved by an average of 15-30% over v1.01 depending on detail settings.
- Smoothness should be improved by an average of 25-35% over v1.01 depending on detail settings; up to 45% in most previously heavy stutter areas.
- Texture size reduction by 35% should also free up some VRAM by a fair amount, regardless of detail settings;
- Existing 1.01 GP Layout has been replaced by what we now call GT Layout; which is the same layout with extra garage spots.
