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.

Now, it just so happens that there are comments on the protonDB suggesting
that in this specific title there are slowdowns (performance loss) Windows
Could you try a few more games for a better baseline. I would really like
