I just updated Retroarch to 1.10.0 and now games play at 2x normal speed, no audio and somehow changes my display settings. After closing retroarch/launchbox, display changes and can barely read text. To fix, I disable HDR setting in Win10. This puts it back to what it looked like before starting Launchbox/retroarch.
Games opened through Launchbox and Big Box all run at 2x normal speed and no audio. So it must be retroarch.
Retroarch audio driver: xaudio
Please help.
