I am playing a game that uses the WINMM API, visibly it has dependencies for more than playing music. On Windows 8 and later, the native WINMM causes the program to run extremely fast, too fast to be unplayable, even at 20FPS lock. The cause of this being WINMM was estimated when a proxy winmm.dll was used from a Windows XP installation that fixes the speed, but presenting input devices' problems. The issue doesn't exist until Windows 7, but the Windows 7 or Vista winmm.dll just crashes the application on my Windows 11 machine (tested on 10 and 8.1 too with same results) . In case community projects are available to fix this, it would be much appreciated if links are provided or if at least, mentions are made as to which WinMM functions are responsible for such speed/time related functions.
