Guys, apply the small update file to avoid exe crashes (RP I would suggest to put the link in BIG BOLD letters as it is easy to be missed by the eye).
As for the update, it' s still hard on the fps, but it looks gorgeous, the objects now blend great together with the environment lighting wise, and the ai is suprisingly good for a custom track.
This mod is right now second to none in custom track quality, I hope that you can make more refinements for fps performance (I think it's time for Kunos to release the mod tools or at least give some advice in regard to performance, AI etc).
ps for the users: For custom tracks uncheck AI colisions to avoid CPU overload for having a full grid of opponents.
