Sausage kerbs
The tires at the inside of corners for preventing cutting corners are replaced by sausage kerbs. These will still prevent you from cutting corners, but when hitting them it will be less dramatic.
3d trees
The old 2d trees are replaced by the newest 3d trees. For seeing these trees you need to have Content Shaders Patch version 0.1.79 (or later) installed. With older CSP versions or no CSP you will still see the old 2d trees. We have tested the impact on FPS, and in our tests it had no significant impact.
Track lights
Not all older GPK tracks did have track lights. With the 2023 updates all tracks will have track lights.
Chicanes
The first and second chicane are changed a bit to make them more challenging.
Banked Corners
The banked corners are still bumpy, but the biggest bump is removed.
