HOW TO FIX D3D9 ERROR ON STARTUP!
My SIMPLE solution to all the people out there who were told to change their DayOne resolution.

Change your screen resolution to 1600 x 900. (This can be found in Control Panel)
Right click Day One: Garry's Incident in your steam library
Click "Properties"
Type "-windowed" without the "
Launch game and enjoy!

I'm not completely sure if you have a different screen resolution while doing -windowed will help
Apparently that's how to "unlock" your desktop!

Right-click the title of the game in your library and hit "Properties". After that, click "Set launch options"
