Nice to see the Super Bomberman R fixes move from Proton Experimental into a numbered release! Seeing as that game was broken between 2018 and 2023, I strongly suspect that these changes are more relevant to the upcoming sequel due out in mid-September, which makes me very happy indeed, as it's my most-anticipated game in years.

Update, added in Proton Experimental update info.

I am so excited for what's coming next, steam deck is moving at an extremally fast rate specially the Godot engine. Like always everything FOSS has proven itself to beat the competition.

I wonder how they even do this. Like, they made the loading screens faster in FF13. Why FF13? Is that just an interesting case in terms of... DirectX code or something? It's really cool (especially since I'd like to replay FF13), just wondering what it is they are trying to find/fix.

Nice. finally updated correctly

Question: On the Deck, is VK_EXT_graphics_pipeline_library always enabled for Proton (8) games or must I manually add RADV_PERFTEST=gpl?
