Bullet Points
– 720P/810P Handheld (Via DLSS upscaling) or 1080P docked (Via DLSS Upscaling)
– Better Texture Quality than PS4 or Series S
– Better reflections than PS4 or Series S
– Better Framerate than PS4
– Similar FPS to Series S Quality mode except in Phantom Liberty
– Significantly better asset loading speed than PS4
– NPC/Vehicle Density on par with PS4 but behind Series S
– Outdoor shadows less sharp than PS4 Interior Shadows improved compared to PS4
– 40FPS mode is kind of pointless as it doesn't hit it in stress tests and Quality mode is actually more stable

TLDR: Sits between Series S and PS4 and plays to the systems strengths with a few random things like texture quality and reflections actually being better than Series S.
