Fucked up lighting and textures.

Heya, i’m having a lot of problems with my Garry’s Mod because everytime i start a new singleplayer game, the lighting and textures are just fucked up.
Props/ragdolls have a lot of lighting in dark/day maps.

I have a texture quality issue too, i have my graph options at the max but i get shitty-looking textures.

Already tried reinstalling gmod, veryfing game cache and deleting my current autoexec.cfg file.
