| Soundwave said: Also DLSS 3.0+ is supported by all RTX cards (so likely Switch 2 as well). It's just the frame generation aspect that only works on 40 series cards, though who even knows if Nvidia is telling the truth about that (why buy a 40 series card if frame generation lets a 20 series card for example double its frame rate). The main thing DLSS 3.0+ adds past the frame generation stuff is "ray reconstruction", which I'm not sure I understand exactly but it makes ray tracing easier and denoises it or something? Sounds like that could help the Switch 2 add ray tracing for a lower performance cost. |
DLSS 3.0 is pretty much defined by optical multi-frame generation.
DLSS 3.5 is the ray construction.
The fact that Nvidia didn't lock 3.5 to their 4000 series gives more credence to their argument that the OFA in the older cards isn't fast enough for 3.0. If it were purely to sell 4000 series chips they wouldn't backtrack and provide support for 3.5 in the older architectures.
Really I think Nvidia should separate the DLSS versions out into different things. DLSS 2.0 should be rebranded DLSS Super Resolution (DLSSSR) & DLAA, DLSS 3.0 should be rebranded DLSS OFG (Optical Frame Generation), DLSS 3.5 should be rebranded DLSS RR (DLSS Ray Reconstruction), and then they could version each one of these as they improve them.
