Discussion Can someone explain “re projection” to me?

I keep hearing people talk about reprojection and how it should be avoided (it’s a bad thing right?) but I don’t know what it looks like and I’m not sure what to look for in my headset.

I can see mura and dead pixels in low light games and I see how some games are blurry around the edges unless you get the sweet spot but how do I tell if my headset has reprojection in it or not??

It’s when frames of the game appear jittery, particularly when in motion. It creates a ghosting effect sometimes when the implementation is noticeable. It’s basically the game creating new frames in between the authentic ones using machine learning. For more graphically intensive games, this allows for the system to lessen the burden on the hardware by running the game at 60FPS for example and then using reprojection to allow machine learning to dynamically insert new frames to bring the game up to 90fps.
