Since 16.3. I have to disable vsync in-game to have FRTC working. It worked pretty well with vsync enabled in-game up to 16.2.1.
Problem: Disabled vsync in game causes annoying tearing. Enabling vsync always on and/or OpenGL buffer on/off won't make any difference.
Why did FTRC & vsync enabled in-game work up till 16.2.1....and not it doesn't anymore. TEARING is not an option.
