Last time I checked (and it’s been a few months), GOG hadn’t updated their version of FO4 with the “next-gen” update that came out early this year. That may be a good thing or a bad thing depending on your perspective because supposedly the update breaks a lot of mods but also is supposed to increase performance.
Is PopOs or mint getting support for HDR? I’m dual booting PopOs but the lack of HDR support is of the things holding me back.
