[Bug 36882] Certain Touhou Games (10, 14, 14.3) run at 20 FPS rather than 60

--- Comment #5 from Andrew Fan  ---
NOTES:

All of the games I tested were done using Windowed 640x480 mode and with all
other settings default. This means 32 Bit Color, Automatic Input Latency, and
No Frameskip (AKA Full Rendering Rate).

Since the same configuration settings were used for all of the games tested so
far (10, 11, 12, 12.8, 13, 14, 14.3) and all of them worked at 60 FPS on
earlier versions of wine, I believe that the configuration settings are not to
blame.

Notably, loading screens sometimes run at 30 FPS, while the rest of the three
games are locked to 20 FPS.

I am currently preparing to do a bisect test.
