Dynamic Resolution not working?

Hello there,

I wonder, can it be that "Dynamic Resolution" doesnt work at all anymore?

I had that active over the past Leagues cause my System is old, and while it gave me the craziest minecraft graphics, I could at least move.

Now I have it active again, but my FPS are low (20~) and it does not change the Resolution at all.

Tried all the render versions and windowed/fullscreen


Edit:
No idea where to delete this post, but I changed some things and now it works lol
not sure what exactly caused the problem tho, maybe it was the Upscale mode? maybe something else, no idea gg gl hf

ty, for me it was upscaling as well, dont delete the post, it helped :)
