Thanks for the kind words. I honestly went straight to that Ubuntu image. I haven’t actually touched the card that came with the Unmatched.
My dual monitors are 1920x1200. I have Displayport out → DVI adapter → KVM for the main monitor.
My secondary monitor is using the VGA out of the sapphire directly to the port on the monitor (I have to switch inputs manually on my 2nd monitor).
I’m not really a benchmark kind of guy, but maybe I should look around and see what’s available to run. Maybe it’s “radeon” vs “amdgpu” after all, but I guess could be CPU throttling? I’m not sure of the nuances between X and Wayland as far as leveraging the GPU.
Sure, moving around in the UI is a bit sluggish, but I’m so eager to find out what is or is not available in apt that I haven’t given the graphics driver a second thought today. It’d be nice to see what’s going on and make things better there, but it’s not crippling my explorations of other things.
I really think the only seriously annoying perf issue I’m seeing is the one in Epiphany…which I’m pretty sure is the JS engine (not V8).
