I have not modified my game in any way shape or form. I have downloaded the game on steam and just played while timing it, you can check literally any other of my runs. The funny part is I thought that run was poorly optimized and a 19 min run is definitely possible. Also I literally had Nvidia FPS counter on the top left fluctuating between 60 and 61 fps. Also I'm opposed to uncapping FPS that just means best computer wins.
