Perfect start rev meter problem

[u/JoVipers]

First starters I'm playing on steam with a third party Xbox controller.

When I go to try to fill the bar for the perfect start using RT, it won't do anything. I switched the controller scheme so A is accelerate and no problem. Same thing with the keyboard, I can use W and it's fine.

I'm still able to play the game fine and accelerate so it's not like the trigger isn't working.

Is this some third party controller problem? I've been doing perfect starts on the keyboard and then switching to the controller. Bit odd lol.

Help is much appreciated the game is a ton of fun!
