Cant move on any map unless i use noclip

no matter what map i load up i get spawned floating in the sky and the framerate is crawling. once i eventually get to the console and enter noclip i can now fly around and the framerate is fine. if i type nolip again the framerate crawls and i cant move. i just did a reinstall of the game and still im having this problem. can anyone help? the only thing i can think of that i changed on the pc was to install quicktime player so i could make the videos.
this is what appears in the console when i load up flatgrass. as i said before i just reinstalled the game so surely there cant be anything missing
