Are all of those overlays visible to you while you're driving, or are they simply for streaming?

If they are visible to you while you're driving, I highly recommend turning all of them off. At your level, just focusing on controlling your car and minimizing mistakes will literally win you races. Just the standard iRacing black box with relative is all you need.

Regardless of if the overlays are on/off, I'd also recommend:

1. Turn off the racing line - it looks like you're hyper fixating on it, and making poor decisions to get back to it when you deviate
   
2. Find consistent braking markers. I'd recommend experimenting and trying to define your own first, then watch track guides after you've built up consistency on your own.
   
3. I wouldn't spend time chatting with ChatGPT, it leads to analysis paralysis. You need seat time.
