Yeah. It's improved by leaps and bounds since DXVK and VKD3D came into existence. Wine was already incredibly robust and powerful with like 20 years of development on it, so Proton combining Wine with those other 2 projects for better DirectX support and then also managing Wine prefixes and tweaks automatically brought us from "if you're persistent and tweak a lot of settings a good chunk of games work" to "most games just work", and now even "if a game doesn't work on Linux now it's because the devs are blocking it actively"

And of course, Valve's active financial support and direct contributions to all of the projects involved has improved the reliability and performance of all of the tech involved by leaps and bounds.
