Will Catalina work properly on my laptop?

[Feartech]

Hey,
I installed Big Sur on my laptop.
HDMI output, Audio, Wifi, Camera, touchpad and keyboard don't working. Usb mouse and keyboard are working. I know that I can fix that with kexts, but I have question before doing that.

System don't work properly, it's lagging, stoping animations when opening something from dock. Can I fix that or maybe I have to install Mojave(If Mojave needs less system requirements) for example?

maybe graphics issue
