I played a bit of it, it's pretty interesting parts look really good while others not as good with a bunch of bugs here and there. I think I still prefer the original graphics, but with more development and tweaking this could be a good way to replay doom.
I recorded a little of gameplay on max settings, it brings my 2080 ti down on rare occasion with 2 light pass, I also did the optional DLSS it offers, not sure if that does anything to performance: https://youtu.be/61x-AKLRoFo
