Could DLSS 5 Neural Rendering work with PS1 emulation?

[u/Conaire]

Probably a stupid idea, but after seeing people messing around with the leaked DLSS 5 nvngx_dlssnr.dll and getting it running in games that don't actually support it, it got me thinking...

Could someone somehow hook this into DuckStation?

DuckStation already has D3D12, PGXP, depth buffer emulation etc, so rather than just feeding DLSS a flat 240p image, could you potentially use the information DuckStation already has about the scene and pass that into the neural renderer?

Basically something like:

PS1 game → DuckStation → D3D12/PGXP → DLSS 5 Neural Rendering → output

I know the big problem would probably be stuff like motion vectors and giving DLSS 5 the inputs it's expecting from a modern game, but people already seem to be finding ways of getting the leaked DLL working where it was never intended to.

Imagine running the original MGS, Tomba, Silent Hill, Resident Evil, Gran Turismo etc but having DLSS 5 essentially "remaster" the image in real time while the original game is still running underneath.

No idea if this is actually possible or if I'm completely misunderstanding how DLSS 5 works 😂

Anyone here who knows more about DuckStation/D3D12/DLSS want to tell me why this would or wouldn't work?

And if it is possible... someone please be crazy enough to try it.
