--- Comment #12 from Patrick McMunn doctorwhoguy@gmail.com --- 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.
