One thing I noticed was even with vsync off, but set to 60, there were times when it wasn’t very smooth and FPS drops would impact the sim, however with vsync off and set to 30, the sim seemed a lot smoother for some reason.
I’m running a RX590 and a R5 3600 with 16gb ram and getting around 35+/- FPS on High settings, with a couple of tweaks.
