For some reason it works only in Fullscreen(limited) and Windowed
In Fullscreen it's only setting 60 Vsync max fps, when it's 75 indeed, in Windowed it's good (75 as intended) but I can't change from windowed to borderless, resolution locks for me, so I have to change to Fullscreen firstly, then to Borderless and Vsync not works anymore...
Not fixed for 1 year+ already :c
