Has it really been that long? Apparently so. Valve originally announced their rebranding of Steam Play with Proton back on August 21st, 2018. Seems like a good time for a quick reflection being halfway to a decade old now with the tech that gave rise to the Steam Deck.
Going from a miniscule library of games that could work (I remember Linux Steam back before Proton having almost nothing of note) to opening up something pretty close to the entire Windows library and running Linux on Valve/Steam’s own handheld console for their games is indeed a quantum leap. That’s what Proton has done for Linux gaming. It may have gotten there eventually just with Wine and community contributions, but it would have taken possibly quite a few years longer to get there without Proton.
I think that is very subjective to the types of games you are interested in. For me Steam before Proton had so many native (indie) games that I literally couldn’t find the time to play all of those I was interested in.
So you agree that your interpretation was very subjective, and many people didn’t have the ease that you had?
No, because going from thousands of games to play to even more that you will never have the time to play is not a quantum leap.
If you had said Proton/DXVK made it finally possible to play a few triple A games I would have agreed. Still not a quantum leap though.
I’ve tried three times to fully convert my gaming rig to Linux, sticking with the effort at least 3 solid months minimum each time. The first time was back in 2015. Only a small subset of my Steam Library worked, despite all of my best efforts hacking on bottles, and there was no way I could stick with it if I intended to play anything with friends. Community aside, Valve and Feral were leading the charge, but I could not stick with it.
My second attempt was around 2019. Almost half my library ran, some in need of care and feeding, others barely functional, but running nonetheless. This was primarily due to my curation efforts of trying to make sure the games I bought offered some slim hope of compatibility. Wine was still a very inexact science, so attempts to get things running outside of native ports or Valve games was a poor facsimile. WineDB representation of compatibility layers was a wide gradient of colors, with most AAA titles still squarely in silver territory or worse. Anything with anti-cheat was a fool’s errand.
My rig’s now been on Linux for 4 months solid, and the state of Linux gaming is nothing close to what it used to be. The state of EAC support thanks to Steam Deck represents a quantum leap all its own, and that wouldn’t have happened without Proton. The overwhelming majority of my Steam Library runs with no effort, each game running nearly as good or better than it did on Windows. This shift did not feel incremental.
Ah, good ole “your opinion is subjective, but mine is absolute”.
