I’m about a year in. One interesting thing is that older games seem to work better with Proton than they do on Windows. For example, after installing Psychonauts on Windows I had to Google why it wouldn’t load and try a few ini changes until I found what worked. On Linux, I just started it and it worked with no issues.
I think people are placing too much on this. Being registered is just sending a piece of mail with a checkbox checked, I think. You don’t even have to donate or anything. I registered as a Republican to vote in their primaries a long time ago, and I have literally never voted for a Republican candidate for any office.
