--- Comment #2 from Zak  ---
After more testing, I have some even more interesting data. After remembering
that wine 9 introduced 64-bit processes for 32-bit apps, I had a suspicion that
maybe it had worked fine before. So I downloaded a wine 8.21 appimage, and
found that the game ran at a locked 60fps there. But after I tried it in wine
9.21, things became even more interesting, because it turned out that the
performance was WORSE than it is now. So some related or unrelated bugfixes
improved the performance.
