The only real sticking points for this port are resolution and texture quality, though. People expecting the texture quality to be better than it is, or resolution to be higher than it is, when comparing the Series S to previous generations because of the specs of Series S compared to PS4/Pro, are missing the fact that other quality settings are different between the two versions. DF didn't mention it in their video but the level with the cherry blossoms have interactive cherry blossoms on the Series S version, while they are absent in the PS4/Pro release. The reflections are also realtime SSR, unlike the cube maps on PS4. And the DOF in fighter intros is on in Series S but not PS4. Both Series S and PS4 versions are missing the sweat details on Ryu during the fighter intro, though. These are likely not the only differences and I'm sure each stage is different, but it's hard to tell because there isn't a lot of Series S footage in their performance review. Regardless, anything extra on screen has some performance cost, be it in memory or FLOPs, even if people don't notice them.
