Regarding your question if modesetting driver is any beneficial: I'd say
generally not, as it doesn't offer every feature of the xf86 DDX driver.
But it can be sufficient in many cases, and I also just found a bug with xf=
86
driver + amdgpu.dc=3D1 causing stutter in mpv. So I'm lucky to have modeset=
ting
as a fallback in the meantime.
