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.
What I did was run the AC Odyssey in-game benchmark, which gave less
than half the framerate I get in the VM version. I'd guess that
probably reflects a worst-case scenario but a brief try at the game
itself convinced me it wasn't playable. Shaders would need to be
recompiled for each scene, which I don't think is practical.
Do you have a link to that video?
