Ok, I've been playing SM2 for a few hours and I gotta say, performance mode is...kinda rough. It doesn't help that I'm used to DLSS for the other games and even for the PS5 versions (I played in non-RT performance) for the res, but performance mode here has a larger gap with Fidelity than I remember from SM:RM and MM, my guess is at least early on it it's probably closer to 1080p than 1440 in many of the scenes for starters. There's quite a bit of breakup and flickering for medium to distant objects as well even when standing still, resembling FSR2 at points.
The thread at ResetEra have noticed this aspect too - there's some bizarre lighting and just poor quality NPC rendering at times, it really stands out. What impressed me when playing SM:RM on the PS5 years ago was how
consistent it was in its image quality, there was so little of 'crap texture outta nowhere' or poorly rendered object surrounded by high quality assets. Here, at least so far, SM2 doesn't seem to maintain that. Again, very early though.
Why so serious?
That beard almost looks like a lower-res mip not loading. In SM:RM, when characters got this close-up you could basically see every pore on their face, this is decidedly muddy by comparison:
I wonder if there's something going on with the LOD in performance, or there's lower quality assets used for it as well in some spots by design?
Watch the trees here as you slide between performance and quality, this kind of resembles what Ratchet and Clank had on PC when using DLSS until they patched it. You're naturally going to lose clarity but the models for the trees actually seem to change, more than I would expect from a drop in resolution. The trees in particular look quite poor in performance overall, party perhaps just due to their design to look more 'thick', but it just comes across as lower fidelity compared to the previous games.
Another comparison overlooking the city, showing the difference in shadow & AO in perf v quality. Maybe it's by design sure, but again, those tree models:
Perf v quality
