Might be down to a higher res but the hair looks a little better, and the shadows are for sure.
There's no mention of it in the article?, so I couldn't say if. I haven't read any mention of it in other reviews either.
Anything could be; there's always something that can be missed. For example, in performance mode, it seems that the XSX has a clearly superior viewing distance in vegetation compared to the PS5 and Pro, and DF hasn't mentioned it either. In the end, these are "small" things. RTGI is what makes the real difference.
Personally, I understand those who see and celebrate a big upgrade if they limit themselves to performance mode and thanks to the RTGI results. But overall, I don't think it's even close to the best Pro upgrades seen.
It's all subjective of course, but I, having a VRR TV, would opt for balanced mode in Pro. Resolution, detail, vegetation, hair physics, geometry... there's too much of a visual difference to weigh compared to 60fps mode. Add the 30fps When in Hideout zone....
In the end, on PS5 at 40fps locked, you have higher resolution, detail, geometry, viewing distance, shadows, and hair physics compared to the game in Pro running at 60fps, with some drops. Something was definitely left undone. Even more so when in balanced mode, there's barely any difference between PS5 and Pro other than the average resolution.
Opinions. Overall, I see decent optimization on all platforms, good work but with also some inconsistencies.
