Kind of.
The big thing that actually defines FSR2 is that it has access to a bunch more data, particularly the depth buffer, motion vectors, and also, as you said, uses data from previous frames.
The camera jiggle is mostly just to avoid shimmering when the camera is stationary.
Under the constraint that I’m only picking from developers who already have multiple games under their belt, it’d be hard to choose between Zachtronics and Supergiant for me. Both of them have a perfect track record in my book. The only difference being that there most likely won’t be any new releases from Zachtronics anymore, whereas Supergiant is only becoming stronger with each release.
