high fps After shipping to server

hello everyone our team already made a physical based game(cars and tanks game)

now in our local computer runs 120fps and works fine,
but after packaging for server cars running like 2 times faster
everything is replicated and works fine in editor

I Also lock fps(using command t.MaxFps 120) but still 2 times faster
in editor 120 fps is works fine and smooth

also after locking to 30 fps in server using above command the game kinda work fine
