Habe es auf anhieb verstanden.

It works imho best for games in the 2014-2018 time range. Newer games work fine but can run at 30-40 fps. The UE5 Games I have tested run only with a lot of upscale (lords of the falling in particular) but still playable.

KeepassXC kann es sogar nativ

Totally missed that part. That is nuts. Thanks

How does this differ from a forced Microsoft login in eg. Forza Horizon 4 or Halo?

Forza Horizon 4 currently

I tried the Epic Version of BL3 (when they gave it away) via Heroic Launcher and that works flawlessly. However I did not yet try online coop.

Currently playing The Finals. Quite nice with the destruction of everything.

It has Steamdeck Support with the same Deck UI as on the official SteamOS.

Had the same issue, but it solved itself somehow. Now I am too afraid to look into it, in fear of triggering it again :D

I am playing my epic games exclusively via heroic and it is a blast.

Played it for the first time some weeks ago. It was like playing Half-Life 2 for the first time again. Loved it.
