[Game is extremely slow]

If you play this video with 0.25 speed, my game is like that:

It's nowhere near the speed of that the original video has.

Hey guys,

When I'm in-game the game feels really slow, like everything is moving in slow motion. If I loose or win a game, everything  jumps and start to move super fast then start to move in a decent speed.
When the units are moving, they are also jumping to another location sometimes. I've tried to set everything in the video options to low and I tried it with different resolutions as well, nothing worked.

Do you have any idea what could cause this?
