Sony PlayStation VR2 (PSVR2)

so they were not using reprojection before ? i'm lost lol
i thought that's what would blur things, but seems it's the opposite ?
I wonder if it's a similar tech to Asynchronous spacewarp on the Meta Quest, which enhance smoothness, but causes artifacting also.

maybe now there is new reprojection algorithm for pro ?

yeah the word positionnal is new here, reprojection in the PSVR1 era was just duplicating frames to make it smoother and creating some ghosting, there it seems different as it removes ghosting, but creates artifacting on some edges.

Solid improvement for vr, new reprojection algorithm eliminating ghosting visable on car when overtaking and in vr replays

GT7 & PSVR2

⬆ Yup I noticed after patch came out.

looks rather easy to fix

i guess it may be using the AI units dedicated to PSSR to do the motion vector prediction thing Mata Quest does with its AI compute to predict head movement and generate the next image, since it's not perfect it generates artifacts, just like a frame gen, i played more, it very apparent on thin structures such as metallic poles, if you look sideways without moving the head those look fine, once you start moving your head sideways you see a lot of "deconstruction" on those elements. But overall it still makes the experience more fluid and clear in the headset.

Noticed visible shimering on Bac Mono front so pros and cons :/ It would be better if ps5pro would be at least 1.5x faster than base and just brute force to 90fps.

And from dev post on reddit:

RSTXIII:
For everyone asking about positional reprojection:

• It has been around for a while
• It is not exclusive to the Pro
• It improves the ghosting effect, but is harder on the GPU than standard reprojection. This is (partly) why many games with reprojection haven’t used it.

Source: Dev. I tested it out for Encircled, but still preferred native 90. For something graphically intensive like Gran Turismo though, it’s pretty incredible.
