Tf2 Turns Dark When Looking At Floor

I can move with wasd just fine but i cant look around at all.
Tf2 turns dark when looking at floor. R flashlightdepthtexture controls something to do with the shadows on textures i think so maybe it s just shadow lighting bugging out which still occurs even when player shadows are off on the textures that would turn black. When cleaning hardwood floors less is more. The moisture is probably the result of. Any server i join when i try to look around i can t i can only see whatever direction i spawn in.
When i play the walls and cieling and floors all flash black randomly throughout thegame but the charecters dont flash its just the walls and cieling and floors. Floors that have a polyurethane finish do not need to be waxed. They may be mold blackened and you may even see water dripping. A small application of cleaner on a microfiber mop is all that s needed to clean your floors.
You right click tf2 in the steam library properties general set launch options and type in windowed. You then go to the in game options put it back to full screen and it should work. Go into the crawlspace under the floor and look for signs of moisture on the joists. Cant look around in tf2 mouse frozen in one direction.
Because i ve noticed the textures in question tend to be indented and are usually on the floor. Does anyone have a fix for this. For fecks sake people look at the date. Its been going on like this for a while now and i ve tried other servers dying and some console actions but none of it.
