I was having this issue where I couldn't use "Game Capture" to capture the game I was playing on RPSC3. I found the problem to be the overlays running on my computer that were interfering with OBS being able to 'hook' the game. I went to Registry Editor and into this directory HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\Vulkan\ImplicitLayers
and started disabling all the overlays I had by changing their values to "1" until OBS could capture RPSC3. The Overlay in particular that was interferring was Overwolf - Overwolf\0.169.0.22\obs\data\obs-plugins\win-capture\ow-obs-vulkan64.json
Don't know if this is the right place to post this, but wanted to help others out who might come across this problem.
