This is an excellent track - one of the absolute best in the AC library. The surfaces and visuals are beautifully crafted, the track is incredibly accurate, and all of the racing features (pit lane, sector times, DRS zones, etc.) work exactly as they should. It is expensive, but it was absolutely worth the sale price I paid for it.
The AI, though, was slow - I was about 2 seconds a lap quicker in their own Rebellion R13, a solid AI car, when I ran it in Weekend mode a few months ago. The stock AI is safe and well constructed - but it just had no pace, particularly in the first chicane and in the stadium section.
I've done my best to up the speed. Kerbs are a huge, huge key to pace here - especially in the first chicane, where a ton of time is lost or gained. I sacrificed two or three tenths on my lap to take the kerbs as softly as I possibly could - and with some DANGER zones and some management, I think this is a decent output.
This is the first AI rework that I've tuned for a Formula 1 car - the RSS 2022, to be exact. It is definitely a pain to get a handle on - but it stresses the limits. They are by far the most dangerous cars here, but I was averaging 1-2 retirements in a 10-12 lap running with the final version of this line and ai_hints.ini. Not bad - and the lap times are really close to the IRL times from that year as well.
Tested in the RSS Formula Hybrid 2022 (shown), the VRC Rebellion R13 (shown below), the TT Cup, the RSS Lambo GT3 EVO, and the Tatuus.
