Major Stuff stops happening in the viewport

[Superlagg]

Ss13 finds new ways to break. So i installed the game on my laptop, and after a few seconds the display freezes. Not like it crashes, scrolling over stuff in the world still shows the name in the down-there bar, i can perform actions on myself and nearby things, and chat works fine (the shitty space rat shows works its id x999) , works that the display stops updating. When I reopen the game, it works for a few seconds, then goes right back to fake lag stasis.

Also my battery went from full to like 5% in no time at all, but i think that's not a byond thing
