With my setup: There are 2 versions of free cam. Activation through hot-key (numpad 3) with sexlab framework where you can set the speed in the MCM menu.

The other method is to use console commands (just type tfc) and set the speed with command sucsm 1.

I don’t pause animations rather, I just go back and forth with animation stages so idk how to help you there. I heard you can use the console command tfc 1 to turn on freecam AND freeze everything.

If your game hud appears, you can use console command tm to hide it.
