As title says, cannot run royals over 60hz when in fullscreen mode, also noticed that for changing high DPI settings, overriding scaling option to make my windows scale larger at higher resolutions, If i go into fullscreen this stops working unless i uninstall the game and reinstall.
Same problem with my PC and laptop. I hope it's not intentional. I found a temp workaround which is to set your resolution to 1024x768, and when playing windowed mode get Borderless program to get rid of title bar so then you get "fullscreen".
