AMD FSR 4 Now Available on Radeon RX 6800 XT with Improved Image Quality and Performance Trade-offs

On September 22, 2025, Hardware News - Graphics Card & Processor News reported that AMD's FSR 4 technology has been successfully enabled on the Radeon RX 6800 XT GPU, which utilizes the older RDNA 2 architecture. This achievement comes after a leak of AMD's FSR 4 source code allowed users to modify and adapt the technology for use on unsupported GPUs, including NVIDIA's RTX 30 series and AMD's own Radeon RX 7000.

Users modified the leaked FSR 4 DLL files to support the INT8 version of the technology, enabling higher image quality with a reported performance hit ranging between 10-20%. This development highlights the community-driven efforts to extend cutting-edge technologies like FSR 4 to older hardware, providing enhanced visual experiences for users despite the trade-offs in performance.
