lazer screen scaling decrease performance

[chrafos]

So recently, I came back to osu! and migrated to Lazer. I'm trying to recreate my old settings playing at a 900p render resolution natively on a 1080p display (to make the gameplay area smaller and compensate for a huge monitor). I found out that changing the screen scaling to "gameplay" slightly decreases my FPS, and changing screen scaling to "everything" tanks my FPS by a huge margin.

Here's the video proof (both recorded with GPU hardware encoder).

Screen scaling everything:

As you can see, with it turned off, I'm able to consistently exceed 500 FPS, whereas the other options struggle to hit 400 FPS. On osu!stable lowering resolution slightly boost fps.

Are you able to test on windows? It's hard to even give advice on windows because the drivers could be at fault (or literally anything else).
