This is a very good track so far, there are some very awkward bumps mid corner in a lot of places, turn 1, 5 and 9 I think, and they are a real handful (for a talentless oaf like myself anyway). But hope you have time to look into it :)
Considering you built this track from scratch and it is still BETA I am extremely impressed. Some guy said it stutters and yet you mention the FPS issue clearly in your description and you mention how you working on the problem. Excellent work. Wish we had more scratch track builders.
