Launchbox with retroarch also suffers from another problem which in the end was accentuated, ie it is the FIRST launch of the game after the initial start. The upload goes intermittently while the bigbox animations continue until the game is started.
@Jason Carr
have you decided how to do with the volume? A solution could be to add in the options the possibility to choose whether to select only if to increase or decrease the volume in BigBox or even in Game, so they are all happy (maybe).
The volume of retroarch in game, is not the volume of Windows, so it is useless to waste time. I see no other solution and return to the old volume model only in bigbox, or you can try this

In the LaunchBox settings (bigBox) it is possible to use 2 buttons in combo for the function) hold + button 1 or 2 etc), in retroarch the volume can be set with a single function key and not with the combo.
If we use the volume from the keyboard, everything works correctly without slowing down. So it's big box that creates conflict with retroarch when we try to increase or decrease the volume in game
New Volume + and - in game = slowdown retroarch (d3d12, final burn)
Please ad option volume in game and only in big box (no in game)
