Open up Steam, right click on GMod, > Properties Launch options > type in -dxlevel 80.
I had the same problem.

dosnt work >.<

windows tells me its a problem with the file “shaderapidx9.ddl” if its of any help?

I have no idea what a .ddl file is, but why didn’t you just Google that error? There’s more than a thousand forums and websites talking about it.

i did google it tried all the different solutuions like "- dxlevel 70 80 81 and so on i tried reinstalling everything installing in differet orders and ive run out of ideas
