DLSS 4 on Radeon RX 9000 is no longer only a forum rumor. Version 0.1.3 of d4r, short for DLSS 4 Radeon, published on October 1, 2026 by developer countervolts, extends DLSS 4 and DLSS 4.5 super resolution to RDNA 4 boards, including the RX 9070 XT, RX 9070, RX 9070 GRE, RX 9060 XT and RX 9060. IT Home highlighted the update and cross-checked it with earlier VideoCardz coverage.
What happened?
d4r does not replace AMD's driver and has no official NVIDIA backing. It keeps NVIDIA's official super-resolution library and redirects CUDA calls through ZLUDA, a compatibility layer that translates the code into instructions an AMD GPU can run. Custom RDNA kernels take over part of the heavier math. On RDNA 4, the relevant technical difference is native FP8 support, the 8-bit floating-point format used by newer DLSS models, so the stack does not need to convert those operations to FP16.
Versions 0.1.2 and 0.1.3 are the ones that open the RX 9000 list. The project's first public release, about four days earlier, targeted the RDNA 3 RX 7000 series. VideoCardz had already mapped the Linux and Proton path: a DirectX 12 game goes through OptiScaler, an NGX API shim and Wine's CUDA bridge before it reaches ZLUDA. On that path, DLSS 4 on Radeon RX 9000 depends on a Linux environment, not a Windows installer.
What the tests show
The developer still treats the package as experimental. The only practical test disclosed so far remains a Radeon RX 7700 XT. In Silent Hill: Townfall at 1440p on the quality preset, DLSS 4.5 reached 49.3 frames per second, below 68.1 for DLSS 4, 71.9 for DLSS 3 and 76 for FSR 4, AMD's own upscaler.
The scope is narrow too. At this stage d4r only covers super resolution. There is no frame generation, no ray reconstruction and no DLSS 5. The documented path also depends on Linux and Proton: it does not run on Windows. That is why DLSS 4 on Radeon RX 9000 is not yet a ready option for a typical gaming PC.
Why it matters
For anyone who already owns a Radeon, FSR 4 is still faster in the only public number. The interest in d4r is elsewhere: it shows that NVIDIA's official library can run, without a modified DLL, on AMD hardware. If RDNA 4's FP8 support lowers the cost of that translation, RX 9000 cards could pull ahead of the RX 7000 series in this experiment. That has not been measured yet. Until then, the project is a Linux technical curiosity, not a replacement for FSR 4.
