This is what I was wondering. Do you think now that insomniac is under sony other sony first party studios will use their tech over CB?
I'd be surprised to see anyone use CB in the next generation.
Pretty much everyone that used it at some point removed it in favour of temporal supersampling.
The last example of it was probably Death Stranding, but at a quick look it seems Horizon 2 is not using it, so it's probably gone from Guerilla's engine as well.
One crucial advantage of temporal supersampling vs. checkerboard rendering is that the latter relies at a fundamental level on the checkerboard structure to work and so the underlying resolution is fixed.
Temporal supersampling makes it easier to integrate a history of frame with different resolutions and therefore plays much better with dynamic resolution.
In modern games the rendering workload can vary dramatically in different scenes so limiting the entire game to a lower resolution because there's an especially intensive spot is not a worthy trade-off (and dropping frames is less than ideal as well).
I think saying that dynamic resolution + temporal supersampling (ML-based or not) + VRS are gonna play a huge role in future games on all platforms is a pretty safe bet.
