I've been maintaining a Ryubing fork that wires NVIDIA's DLSS 5 stack into the emulator: DLSS upscaling + DLAA, Neural Rendering (toggle with F6 in game), and DLSS-G frame generation up to 4x.

The frame gen is the headline: 30fps-locked first-party games play at a solid 60 with 2x, and 4x gets past 100 on a 50-series card. The status bar shows the effective rate (30 FPS FG x2 60 FPS) and DLSS/NR/FG are all live toggles, no restart needed.

Upstream Ryubing master gets merged in automatically every Monday, and the build self-updates. Windows + RTX only (frame gen needs a 40-series, 3x/4x needs a 50-series).

Honest caveats: the frame gen guides are static for now (an emulator can't see the game engine's motion vectors), so HUDs and fast camera pans can warp. Hardware optical flow is the next milestone.

Downloads and changelog: ryu.dotslash.pro - bring your own keys and firmware, obviously.

The repo itself stays private because the proprietary DLSS runtime binaries live in-tree, but the emulator source is MIT like upstream - DM me if you want the code.
