With or without HDR my ps5 has still crashed. Reinstalled DT. I took my resolution to 1080p without the HDR on and look like ps3 era washed-out ugly and with jagged edges. Other settings may have crashed my ps5 but it was pretty to look at. I changed so many setting tried, so many things yet nothing has work. I might have to just wait for a hotfix or launch.
yes 120hz is off been asked more times then I like today< small vent
UPDATE: in the game setting turn on fame rate to 30 fps this fixed my over heating/hard crash issue. And I set my graphic back to 4k played for few hrs in the Tural doing cs, walking around areas in the city with lots of people no crash.
My fc leader looked around the jp forums saw some post 30 fps as bandaid solution until this gets patched.
I hope this fix works for others.
