So, the headlights in GSC aren't best optimised. We don't use them in the club because it can cause people frame rate issues. But there's been a lot of updates since I was told that nearly a year back, and there's this tip: Open your prl file with notepad++ (right click) located inC:\GSC2013\UserData\YOURNAME Find the line 277 and correct it like this : Max Headlights="10" . You can try other values. So, my question is whether anyone runs night races successfully? In what vehicles, etc, and whether people would mind testing out night races and posting here how it went (I run night races at some tracks without any problem on single player vs the AI). I'd like to run some night races in the club, but unless most people are able to run them smoothly, it's a no go area right now, which is such a shame. Feedback, pretty please, and thank you.
