PS5 version VS PS4 Backwards compatible version?

[Vahlnir]

Still doesn't change the fact it's performance in terms of frame rate is bad in both 1400p and 1080p. It's not just Limsa but most opened area will have frames dropped for no reason. The PS5 version should have stayed in beta. That being said you can run the PS4 and get consistent 60fps in both modes and load slightly slower than PS5 version.
Don't think instanced zones suffer from frame rate drops.

Yeah, the fps drops in full 4k on PS5 are pretty bad. Playable, sure, but I like my juicy framerates. I have a 4k TV and one would think it would run better than it does. The middle ground, UHD I believe its called, provides the best of both worlds but even then there's still some fps drops depending on the location, some worse than others. I think it needs optimized a bit better. There's no way it was ever ready to leave beta. The PS4 Pro optimization worked so much better.
