Noticeable lag when turning on Hidpi mode on Hackintosh with Has Ryzen 5 5600H about betterdisplay

Hmm. Something looks weird here. I don't think there is a Mac with a built-in display that has 1920x1080 as native resolution and 120Hz. I see that it is not an XDR display from the menu but non-XDR built in screens don't have 120Hz. What platform are you on? Or is this Intel/Hackintosh? If so, what GPU does it have?

(Ok, I see it's Intel from the "Aim for a HiDPI default resolution" - but then is must be a kind of Hackintosh notebook, right?)

yeah it's an hack, it Has Ryzen 5 5600H with full graphic acceleration (2gb allocated). It's running from the igpu and the screen native resolution is 1920x1080 on windows

would like to add that scalling works perfectly on the above configuration, it's just that it's laggy in animations.

I see. Well, this seems to be a driver issue, it might be that the hacked driver is not optimized for a 4x framebuffer size for some reason. I am not sure which driver it uses but if it is the basic EFI framebuffer driver then a slowdown like this is expected. If it is a kind of accelerated driver (one of the AMD drivers?), the maybe something is not configured well? Do you experience the same with external displays?
