I haven't played through the entire game to verify complete integrity, but the game seems to be playable with obvious temperary visual glitches (i.e. textures disapearing for less then a second, noticable but playble). I used the demon souls custom configuration settings, vulkan gpu with write color buffers enabled. I played all the way through the tutorial area, picked up items, killed the boss, and triggered the cutscene to leave. I addition I was able to level up. Based on my experience, I would assume the rest of the game is playable if visually glitchy.
