Here recently it did this converting to a more efficent format. Afterwards I tried playing Garry’s Mod and when I joined a server I could not see any players, only their shadows, physgun, and there names. I also noticed a weird assortment of colors on different textures and objects. But the weird colors went away because i changed the launching options to -dxlevel 80. I still have a few problems.
-Missing Playermodels (invisible)
-Missing Revolver (invisible)
Please try and help. I have CSS and TF2, L4D1 & 2 all installed.

I just realized when I went into singleplayer I have no hands on any of my guns, and when I went to go spawn a Zombie NPC the game froze and crashed with no error report whatsoever
