It works fine but there's a huge loss in detail between the fidelity and performance modes. Why couldn't they get a higher res at 60 on ps5 considering how the graphical improvement over Part 2 us relatively minor?
Same as why Demon’s Souls is 1440p 60. That’s what the PS5 can lock to reliably.
3840 * 2160 * 30 = 248,832,000
2560 * 1440 * 60 = 221,184,000 (89% of 4K30)
Similar pixel fill rates. 4K30 and 1440p60.
The next common resolution above 1440 that offers a noticeable improvement is 1800p.
And 1800p @60 is significantly higher pixels/second than 4K30 and 1440p60.
3200 * 1800 * 60 = 345,600,000 (139% of 4K30)
