This thread is hilarious on so many levels. Not just because you're wrong, and completely misunderstood what was said in the video, but also because I'm pretty sure I saw you in another thread telling people they need to watch the PS5 game presentations in 4K on youtube to really appreciate how good they look. Now suddenly 4k is a waste of power. Classic.
Suddenly DSLL is waste on Xbox SX and Nvidia GPU . Now many GPU implemented DLSS which is checkerboard rendering
DLSS 2.0 is not checkerboard rendering...It's an AI taking higher quality image like a 16k image and actually creating a lower resolution image like a 4k image. Or it will take a 540p image and reconstruct it to 1080p making it a very sharp 1080p image.
Nvidia has a dedicated video explaining what DLSS actually is: https://www.youtube.com/watch?v=0X1RtXCvPFQ
Yes, this is nvidia tech so it's not available on any non NVIDIA cards, the only console that may use it in the future is the switch 2. Nvidia uses DLSS 2.0 on their Nvidia Shield pro tv which mind you the shield is practically a nintendo switch. It's a nifty piece of technology that will free up a lot of resources. Checker boarding is no where near what DLSS 2.0 can do.
