I am not bad with computers and have a beginner+, maybe intermediate level knowledge of Linux and I kept running into some problems here and there with different distros. Most claimed to work out of the box (which may be the case for some users, but I have a shit ass Nvidia 1060 and that was not at all the case, until I installed Nobara KDE/Nvidia.
Just came here to potentially save someone time, this shit is actually working out of the box, closest experience to this was with Arch, but that’s definitely not out of the box.
I got Helldivers to work by making it open in windowed mode rather than full screen, then making it full screen once it opened. Seems to be a common issue with it. someone on protonDB mentioned it iirc.
