Gravity and jumping is wierd

Hello. I reinstalled windows on my computer and then after i have installed Unity again something was really weird with the gravity and the jumping.

The gravity was really weak so it took vary long time to get down so i changed the gravity in the physics menu to -200 to get it work as i want.

Then I jump it’s not really a “jump” more like a teleport to a position and then fall down. I use rigidbody.addforce for jumping.

Any idea why it doesn’t work as i should?

Maybe it’s because of lag? Re-installing windows might of made your computer slower.
