My PC is a potato by today's standards, but it's a pretty decent machine by
2013 standards: Dell Optiplex 745 with 8GB RAM, CPU upgraded from stock to an
Intel Core2 Extreme Q6800 @ 2.93GHz and a Radeon R7 240. This desktop dual
boots Gentoo Linux and Windows 10 Home. Under Linux with the latest version of
Wine, Arkham Asylum runs at a barely playable, slow speed even with every
graphics setting disabled or at the minimum -- even with the resolution as low
as it will go at 640x480. But under Windows 10, I can play the game at full
speed on those same settings with the only noticeable momentary stutter in
frame rate when I enter an area that has to load new area data. Under Windows
10, I can max out all the graphics settings and play at a maximum resolution of
1920x1080, and while there is definitely a noticeably lower frame rate than
when at lower settings, it is still at a playable speed and faster than under
Linux at the minimum settings. The quality of the experience is very different,
though. Under Windows 10 at maximum settings, the game still runs at close to
normal speed but with a lower framerate. Under Linux at minimum settings, it
just seems like the game is in perpetual slow motion (which gets REALLY bad
once you get out of the first part of the game in the underground facility and
make it to the surface of the island where lots of things are visible in the
distance).

This is a dual-boot machine, so the comparison is on identical hardware. There
is clearly something going on here. I don't know how much a difference the
quality of the video drivers is making, but it is hard to ascribe the
astounding contrast in performance to just graphics driver performance.
