It's taking a temporal Resolution from the previous
frame and and injecting them into the new
frames image, while jittering the pixel count to a higher resolution... It can be done at
1080p 1440p or 1800p to resolve at 2160p when using a 4k
frame buffer... This is what Insomniac has used on both Ratchet and Clank and Spider - Man... The Technique was developed by Epic games and then used by Ubisoft for For Honor on PS4 and XBOX One X...
Whether a game streams at 30 or 60
frames per second, you'll be able to play it in full
1080p with very little
buffering and only a few moments of lag or stuttering.
