Optimal RPCS3 settings for Steam Deck?

Hello! I have recently received my Steam Deck, and have been in the process of setting up emulators. This week, I focused on RPCS3. I installed firmware and then tried two games - Journey and Deus Ex: Human Revolution. Both games installed and opened. However, Journey has lots of artifacts appearing in the display randomly, and Deus Ex freezes soon after startup. I know that not all PS3 games run on this emulator.  I was wondering if there is a recommended configuration to use with the Steam Deck in order to get the best possible performance.  If certain games require a custom configuration, that would also be helpful to know.  

Thanks for your assistance!
