I just installed it and it seems to work out-of-the-box for me on Ubuntu 23.10 with a AMD 7900 XTX and AMD 5800X. I'm getting around 55 fps at 3440x1440 with almost everything high beside having disabled V-Sync, DoF and Motion blur. AA set to TAA 2x.
No they are not: F-Droid builds a signs the apps independently. Source: I have apps on both stores.
All F-Droid apks are signed with a different key than the play store one: you do not upload your key when you publish on F-Droid and all the apps are built from source by the F-Droid build servers.
Interesting. But should this apply to many apps on F-Droid? I also have an app published on both the Play Store and F-Droid and I don't recall having seen requests to change the application ID to avoid clashes between stores.
