EA recently sent Origin to the graveyard and replaced it with the EA App, which caused numerous problems on Linux desktop and Steam Deck but it looks like the biggest problems are over on that.
The problem is that these extra external launchers can cause a number of issues for the Proton compatibility layer. This is because Valve (and their open source contractors who work on Proton) need time to catch-up on the compatibility side. The switchover came with problems, which Valve partially solved a week later but it still had issues leading me to do a guide on getting it working again. Another few weeks later, Valve put a proper fix in to stop the EA App failing to update.
With that all done and the dust settled, Valve has now gone back through multiple problematic EA published titles to re-review them for Steam Deck compatibility.
- Battlefield 1.
- Jedi Fallen Order.
- Sims 4.
- Titanfall 2.
All officially noted to be playable again, with Valve setting them to use Proton Experimental by default.
Nice to see Valve do go back over certain titles to check them again, although they really need to do that for God of War that has a bug that can reboot your Steam Deck.
