First of all, I did not know that, but you can install the Steam version of Eve and still play with your normal account.
The new launcher also works great out of the box.
I’m using Proton Experimental.
AMD FSR 1.0 also works (at least with a Radeon card).
I usually run Eve in potato mode, now I can run it in super potato mode.
I understand that many people here want to avoid Steam and I guess some of them due to large amount of dependencies that the client brings.
However the flatpak version works great.
If you want a simple way to install Eve, you should give it a try.
