No, it's not about whether to disable Discord hardware acceleration (which is clearly disabled), but it's an Osu option, "Render at native resolution", I play in full screen 1080p, but I had it enabled, after weeks of searching for a solution, that was the problem, and not only that, but it went from 0.5ms to 0.3ms, I hope this helps someone too.
Also disable the "Reduce dropped frames" and "Detect performance issues" options, and disable "compatibility mode".
I'm using Google Translate, sorry
