I had two people today asking me about an error which caused Arma 3 to not start.
The error was "Fatal Error: F:\SteamLibrary\steamapps\common\Arma 3\Dll\x64\GFSDK_SSAO_D3D11.win64.dll could not be loaded"
Image of the error:
RPT Log only stated that error above and literally nothing more (sadly don't have the logs right now).
