Getting poor performance on KDE Plasma / KDE Neon

I love kde and kde neon, but i have some problems with performance when using it. I suspect that is something related to gpu driver, cause the cpu gets high level usage when i do such simple graphical stuff like just scrolling down a page (on vscode the cpu goes to 100% usage).

I know that's probably not the best param to show it, but: I used glmark2 to benchmark on kde neon 5.18 and linux mint 19.02 over the same pc. And I got:

- score 1077 on linux mint 19.02
- score 592 on KDE Neon 5.18

I have a AMD R7 m445 graphic card.

$ glxinfo | grep "OpenGL version"

I'm getting bad performance too, a few months ago is going very well almost smooth but now is awful, freezing application, slow boot, slow login screen to desktop is the same hardware, the same configuration, the same applications, the same nvidia graphics card (9500 GT).

I'm on KDE Neon since 2019 but with new updates is getting worse, i'm gonna try other distro because have a some time now (quarantine thing)
