I'm looking to reduce lag as much as I can to speed up the game. From what I can see, my game is much laggier than other runners'. Is there a specific tip or platform that could help with this?

I have the same problem, i hope u find a solution.

I really only have this problem on the time is money mission, I really just try to play through it and hope it doesn't last that long

The best way to reduce lag for me is to go into the pause menu and lower the quality settings, remove camera shake, and lower gore settings. It takes a second or so to do, but does ultimately speed the game up which I consider a good trade off
