TL;DW:
Quality modes:
-PS5 and Series X are Native 4K, Series S is 1440p.
-PS5: Runs around 45fps, never drops below 30.
-Series X: Runs around 40fps and is generally around 5-6fps lower than PS5 in like-for like scenes.
-S: Just slightly above 30fps most of the time.
Performance modes:
-Performance modes on the current-gen consoles feature worse shadow quality but other settings (foliage density and draw, effects, textures, ambient occlusion) are equal to the Quality mode! Only other difference is that Series X|S lose motion blur in performance mode whereas PS5 keeps it in all modes.
-PS5: Targets native 4K but is generally 1512p to 1800p. Runs at 45 to 60fps depending on the scenario.
-Series X: Targets native 4K but is generally 1512p to 1800p. Mostly 1512p though, often a lower resolution than PS5 in like-for-like scenes.
-Series X generally runs worse than PS5. Just walking through the grass sees Series X struggling to reach 60fps. PS5 has a 10fps lead sometimes.
However there are outliers which favour Series X; rapid traversal on horse back for example. Riding one particular path via horse gives Series X a 10fps advantage of its own. For the bulk of gameplay though, PS5 has better framerates.
-Series S: Same settings as Series X and targets 1440p but seems to actually be around 1008p. Runs between 40-60fps but is generally around 50fps
Loading times:
-PS5 trumps all versions, with loading times that are around half that of Series X|S in all situations.
Notes:
- No ray-tracing in beta but it will be an option at launch.
- Running PS4 Pro version on PS5 gets you Checkerboarded 1800p and lower settings but you get a practically locked 60fps!
- DF are unsure whether the missing motion blur in performance mode on Series X|S is a bug or on purpose to help performance.
