I recently bought a dock for my Steam Deck, and was trying to play a Super Nintendo game through EmuDeck Retroarch last night. The input lag was so bad that I couldn’t really make it through a level.

I’d press jump and then……jump!

I was using an Xbox One controller that I have no issues using with PC.

Is the lag from the Deck? Is it retroarch? The snes9x core?

Not sure where to begin diagnosing this one.
