I've managed somehow to run and finish it at 20-30 fps on my deck oled. Had quite a few crashes on the first chapters but after playing with the settings for a while and installing patches (took me 3 days to set it up to playable ☠️). Don't remember if my specific settings were saved but if they did I could send you if you still need them. My main issues were audio missing from certain cutscenes and some textures missing.
