This one's a tad more closer to actually "being there". However, in my previous release, I was mistaken, while the command will sometimes lead to using the wayland backend, it's not consistent, the only consistent method I've found, is setting the registry key, simply create an empty text file, call it wayland.reg (the name actually doesn't matter, just the extension) and fill it with this
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Wine\Drivers]
"Graphics"="wayland"
Then using protontricks, select whatever game/program you wish to run, it'll complain, just click okay until you reach the menu, select the default prefix, run winereg, click flile, click import registry key, and import the .reg you created. It will then start in wayland...or it'll crash, but that seems very few and far between this time around.
Noteable issues I've found with this build:
First is mouse acceleration, it will either be fine, or way to sensitive, not much I can do about it, but in the vast majority of cases, it's fine.
Second is scaling, if the screen isn't windowed, it'll probably be the wrong resolution for your monitor, same as before, not much I can do.
Finally, controller support, it seems extremely hit or miss. This may be steams input being weird, or something else, but I don't know what causes the issues.
