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
One modder has reverse-engineered DLSS 5 to function on RTX 4000 series Ada Lovelace-based GPUs, porting incompatible CUDA instructions within the Neural Rendering DLL, enabling them to be read on previous-gen hardware.
Modders have successfully ported Nvidia's DLSS 5 to work on RTX 4000 Series graphics cards, despite the initial compatibility issue with CUDA instructions. The leaked release of the DLSS 5 nvngx_dlssnr.dll sparked interest among modders, who integrated it into various titles outside of Remedy Entertainment's Control. The early access version of NBA 2K27 contained a new file enabling the Neural Rendering technique, which was later ported to other games.
The RenoDX Discord server served as the hub for this development. However, the current binary only works with RTX 5000 Series Blackwell GPUs due to the incompatibility of certain CUDA binaries with previous-gen Ada Lovelace hardware. Modder Uncle Burrito addressed this issue by patching the DLL file to work on Ada Lovelace hardware.
This patch has been verified to work on an RTX 4080, and multiple versions of such patches are being developed by other developers within the RenoDX Discord server. While official DLSS 5 support on non-Blackwell hardware remains uncertain, the modding community's progress suggests that Nvidia may consider releasing it for previous-generation GPUs.
However, supporting Ampere GPUs and older may prove challenging due to their lack of native FP8 support.
