a commercial version of WINE

That would be CrossOver by CodeWeavers. They’re actually a huge contributor to upstream Wine and have worked with Valve (and I think Collabora?) several times over the past few years. I’m kind of tempted to buy a copy of CrossOver to support them even though I’d never use it, lol

That’s a perfect way to put it. From constantly relying on ProtonDB to occasionally checking areweanticheatyet.com.

Mindlessly watching glxgears is the greatest experience a GPU can render.
