Thank you for this mod, you have done some quality work. There are minor issues with the placements of some of the items which I'm sure will be fixed soon, the fps is okay on my old laptop, it can run it around 55fps just like any modded track. I had to install the shader because without it I couldn't load the track at all.
I have a minor issue though, I don't know if the tarmac you used is less grippy or something, but I have serious problems driving the normal version of the track, I slide all over the place, for some reason I find the wet version to be easier to drive on.
