In play editor it is only working for the physics simulation when it is below 1, so only slower and not faster. Tried Global Time Dilation and the slomo console command. As a Standalone it is working faster but only to 2x speed. So when you set it to 4x everything will move at 4 times the speed except everything physics animated which is stuck at 2x speed.
The funny part is even though > 2 does not change the speed of physics it still messes with it, stuff that perfectly orbited my sun now goes straight into the sun. (I’m changing the Time dilation before anything starts) I’m using radial force and Impulse.
