Right. I believe what happened was when Mascot shared his Detroit Street Circuit that was redone here, it spurred a question about the two being different (Belle Isle). We had talked about how the Belle Isle track has poor road mesh - too smooth - and could use a bit of a texture or skin update.
The Detroit Street Circuit is fine (although the road color is way too dark for downtown Detroit, have to switch that out). We don't use that circuit here anymore. IMSA, INDY and Trans Am as well as others use Belle Isle, that's why we were talking about the update.
People seeing that the two tracks were different started a complete confusion festival.
Wow, thank you very much for this. Wunderbar!
Go into data folder. Open engine.ini and ai.ini. Make sure that the upshift of the ai is BELOW the rpm limiter, say by around 200 lower. You should be good to go.
