📋 About This Mod
If you have any doubts that it's not working, then you can simply see the video on this page that is running on a 144 Hz monitor. FPS counter in the top left.
When you have set it up correctly you will have:
Lips in sync regardless of framerate.
Animations in sync regardless of framerate (no speeding up/down).
No spasming ragdolls regardless of framerate (i have played this game for hundreds of hours without encountering it).
No slowdowns when you are below your refresh rate target.
Correct weight/gravity when moving around bodies and items regardless of framerate.
You can read more here about physics implementation in games if you want to learn more:

if it's not working for you, something is set up incorrectly. This is the result of a correct setup:

However this is not enough, I will explain what you need to do below.
Physics time table
This sets frametime* (not the same as FPS) for physics.
Simply divide a timeunit(hz)/second by your framerate target.
For example: 1sec/60fps = 0. 0166.
Magic, your fMaxTime is = 0. 0166. Aka your frametime for a 60 fps monitor. Don't worry you don't need to understand this, see below.
fMaxTime=0. 0333 is for 30fps
fMaxTime=0. 0166 is for 60fps
fMaxTime=0. 0133 is for 75fps
fMaxTime=0. 0111 is for 90fps
fMaxTime=0. 0083 is for 120fps
fMaxTime=0. 0069 is for 144fps
fMaxTime=0. 0042 is for 240fps
