I would really like if you could do some track optimising, your track with every version is getting worse on frame rates. Guess that goes together with your attention to detail policy and thats nice but eh... I would really like to be able to REALLY RACE HERE. :S Now I'm even struggle with fps when I'm alone on track !?! If you wish, I can nake you so many great, great track around here, with so many details but with so much better optimisation. Try Macau, for example. So pretty and so CITY track. But you can add as much car as you wish.
Or if you can't do anything about it, I'll use some of the first track versions, they look almost the same to me...
