I'm an adult with a job, and I don't have a snowball's chance in hell of affording the recommended system requirements for this game any time soon. RX6800XTs do not grow on trees.
If you've got windows 10 try updating to 22h2 (no, really; a consequence of Bethesda being acquired by Microsoft, I suspect), and update your GPU drivers.
That got it running on my 980ti, so it should also work with the 1070.
Yeah, I think it's probably having to do with how Wine/Lutris emulates the Windows version, that makes it think it's an older version. I'll try on a real Windows partition...
Did u try adding it as a non-steam game directly on Steam and not using Lutris? I've tried both on my EndeavourOS PC and find that for whatever reason, it runs much better via Steam vs Lutris.
