DLSS 5 Successfully Runs on AMD RX 9070 XT: Technically Possible, Frame Rate Crashes From 80 to 12

DLSS 5 is NVIDIA's marquee feature for the RTX 50 series, locked to its latest cards. A modder recently ported it onto an AMD RX 9070 XT — it does work, but Cyberpunk 2077's frame rate drops from 80+ down to 11–12 FPS.

DLSS 5 is NVIDIA's marquee feature for the RTX 50 series, locked to its latest cards. A modder recently ported it onto an AMD RX 9070 XT — it does work, but Cyberpunk 2077's frame rate drops from 80+

How it works: drop dlssnr_on_amd_setup.exe into the game's bin\x64 folder, place NVIDIA's nvngx_dlssnr.dll (version 310.8.0.0) next to it, run the installer, then in-game turn on FSR upscaling and press End to refresh. Why it works at all: this generation of DLSS 5 neural rendering runs on FP8, and AMD's RDNA 4/RDNA 5 GPUs natively support FP8 — so the hardware wall doesn't exist; the 'lock' is software-and-driver-level, which is exactly what the modder bypassed. YouTuber Ancient Gameplays confirmed it works on RX 9070 XT in both Cyberpunk 2077 and GTA V Enhanced Edition. Performance cost: the same RX 9070 XT that runs Cyberpunk at 80+ FPS without DLSS 5 NR drops to 11–12 FPS with NR on — basically a slideshow. The neural renderer was tuned for RTX 50 tensor cores, and on AMD it has to fall back to general-purpose compute. The latest alpha (v0.2.7) bumps it up by 12% (Cyberpunk at 1080p hits about 30 FPS), but that's still far from playable. Online games with anti-cheat block the foreign DLL outright — this mod only works for single-player titles. AMD isn't the first frontier cracked: in the same week the community has already ported DLSS 5 NR to RTX 40, 30, and 20 series, and even got it running inside the PCSX2 PS2 emulator. The pattern is the same: it runs, but performance falls off a cliff. An earlier RTX 3080 test even went from 138 FPS down to 4 FPS. NVIDIA's official line: DLSS 5 optimization will prioritize RTX 50 first; RTX 40 support will come later, after the model is tuned. Bottom line: this whole chain of mods is more of a tech demo — proof that 'exclusive' is not an uncrossable wall, since FP8 hardware can run anywhere. Actually playing games on it, though, is a different story. Being able to run, and running well, are separated by an entire stack of vendor-specific optimization that no single DLL can replace.
