Game in slowmotion when frames are locked at 60 fps

Hey, thanks for explaining

Same question to you does it also work when you package the game or is this just for in the viewport?

Also I was wondering if you knew this: why is my fps only 40 in the first place?
I tested it aswell on a completely new project (packaged aswell, videos above here were also packaged) and also had 40 fps, now I play on 2560x1440, but it seemed weird to only have 40 fps even in a game with almost nothing in it.

Thanks
