      Hello Folks,
      I am running Retropie 4.3 on an x86 PC. The operating system is Linux Mint. The hardware is a AMD A10-7860K and motherboard is an A86hi-ac.
      When I have the PC connected to a PC monitor, everything works great. However, when I connect it to my TV, RetroPie runs slow in all emulators, the audio is choppy and it runs appx 10fps.
      This only seems to affect emulators, the menu interface is smooth, and all other functions in Linux are normal. Kodi embedded in Retropie runs perfect.
      I've tried hard gpu sync, running at native resolution, and I'm out of ideas. Any help would be appreciated.

        Are you connecting via HDMI? On both monitors?

          @boosef16 I suspect this has something to do with the setting on your TV. Is there a game mode or something similar on your TV?

          https://github.com/RetroPie/RetroPie-Setup/wiki/Speed-Issues <<<this page in the docs covers issues possibly relating to TV settings you may want to try.

              I’ll try your game mode as soon as I get home. Sub note, I put retropie on a raspberry pi 3. Same tv and same hdmi cable and it works perfect. Thanks for your time marky.
