Nothing unique about the release, proton gets better and better. There are some games however that will likely never work, because their studio or developer blocks it. Most of these are competitive shooters. As long as you are OK not playing these, any time is a good time.
Not only that but they helped reach critical mass to drive adoption, and used their dominance in the industry to push studios to work with us, instead of against us.
Significant for me. Not sure if vsync is working.
