It's been running great for me (3080), but I left everything on default. The only issue we've had is the game has crashed for one of our party about 4 times when going through doors. It's saved progress all but one of those crashes.
Overall, it feels like Remnant 1.5 - same generally loop and just a bit more polished. But that's great. It's exactly what I wanted.
They just made a post yesterday promising performance patches, but I think it's important to understand the issues I mentioned won't be fixed.
Frame drops and stuttering? Sure, they can fix that.
Designing your rendering system and performance targets around the use of DLSS/FSR? That won't change. Blame the PS5 and new Xbox for that. A lot of AAA games are going to be like that for a while.
