Blacklisting the i915 didn't work, so I changed the BIOS settings and
that did it.
Unfortunately, although some games work well (e.g. Witcher 3), others
don't (Assassin's Creed Odyssey - lots of stuttering), so I'll probably
back off from this for the moment, though a more high-end GPU might
have better results (mine's a lowly GTX-1050). It's interesting that
the GPU passthrough with QEMU/KVM works so well in comparison, given
that it's a whole virtual machine.
I don't thing the 1050 should be THAT bad... I did just watch a youtube video on gaming on linux and it specifically talked about some games need to compile shaders on first run. You could try leaving the game running for 10-30 minutes and see if it improves.
Thanks,
