DLSS 5 Patched to Work on RTX 4000 "Ada Lovelace" GPUs Despite No Official Support

Modders have patched NVIDIA's leaked DLSS 5 neural rendering tool to work on RTX 4000 "Ada Lovelace" GPUs, despite the tool being built only for RTX 5000 Blackwell hardware. The patch, created by modder "Uncle Burrito," swaps incompatible binaries for Ada-compatible ones, and Tom's Hardware confirmed it works on an RTX 4080.

The modding community has been hard at work https://www.techpowerup.com/352076/dlss-5-gets-modded-into-skyrim-with-dramatic-changes-to-lighting-and-character-faces ever since the untimely release of DLSS-NR, a precursor to DLSS 5. Now, modders have gotten NVIDIA's leaked DLSS 5 tool working on RTX 4000 series cards, even though the tool was only built for RTX 5000 Blackwell hardware. The DLL leaked earlier this week via an early-access build of NBA 2K27 https://www.techpowerup.com/352026/nvidia-dlss-5-neural-rendering-dll-leak-hints-at-nearby-launch , and people on the RenoDX Discord quickly got it running in other games using ReShade and RenoDX. As we noted in our DLSS-NR breakdown https://www.techpowerup.com/352033/nvidia-dlss-5-dll-leaked-by-nba-2k27-early-access-build-heres-our-analysis , the AI model runs on FP8, which Ada Lovelace GPUs support just fine, but the compiled binaries inside the file only targeted Blackwell's sm 120 architecture, with nothing built for Ampere or Ada. A modder going by "Uncle Burrito" has apparently fixed that by hunting down the incompatible binaries and swapping in ones built for Ada. Tom's Hardware confirmed https://www.tomshardware.com/pc-components/gpus/exclusive-dlss-5-has-already-been-ported-to-work-on-rtx-4000-series-graphics-cards-incompatible-cuda-instructions-get-patched-to-work-on-previous-gen-hardware the patch works on an RTX 4080, and said other developers in the same Discord are working on their own versions of the fix.
