Extensions are not equivalent to native customization, and both have pros and cons. On one hand, extensions provide a variety of features that can be added specific to people’s likings, but on the other hand, there are chances of incompatibility (in gnome shells for example) and delayed maintenance from developers (which results in having to wait for them to finish the work when dependency updates)
That’s disappointing. From Capcon’s even earlier track record such as DMC5, RE 2/3/4/8 and MHR, I expected great builtin compatibility of their RE engine with Linux and Steam Deck. But their latest titles DD2 and SF6 proved otherwise, so I guess it’s just optimization problem for specific game cases
