The modding community has been hard at work 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, 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, 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 the patch works on an RTX 4080, and said other developers in the same Discord are working on their own versions of the fix.
