GPU is not recognized


Some NVIDIA Optimus users can have troubles getting Substance Painter to run on the right GPU. A workaround is to set the following keys in the Registry of Windows to 0:

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\RequireSignedAppInit
  • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows\RequireSignedAppInit
