Rendering and other toolguns not working.

EDIT: Someone fixed the problem. Put “-dxlevel 90” in your launch options.

The toolguns under “rendering” and some more tool guns are not working. I have tried re installing gmod and even deleting gmod folder in SteamApps. Nothing has fixed the problem. I have also noticed that props materialed with material tool do not show new material. Problem persists in single player.
