RedStickAdam 19 Posted August 26, 2018 "Failed to create D3D9 device. This may happen if the desktop is locked. Exiting..." Any fixes? Brand new PC. Like, not even 24hrs old. All drivers are up to date (to my knowledge). That being said, I am using a custom (NOT DEFAULT) PC resolution. I've tried the machineoptions.ini fix, and Steam command line stuff, which did not work. Help? Quote Share this post Link to post Share on other sites
