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!

Journey is not Playable and Deus Ex is only Playable on the regular version.
If the game is not listed as Playable, don't even bother trying it on Deck.

If you want to know specific settings, check the wiki pages for the games.
