Introducing FSR 4.1.1 INT8 Leak and Its Potential Impact on RDNA 3.5 Architecture
In a surprising turn of events, Valve accidentally leaked the FSR 4.1.1 INT8, sparking curiosity among gamers and tech enthusiasts. According to a Redditor, this leaked version of FidelityFX Super Resolution (FSR) has shown compatibility with RDNA 3.5 architecture, hinting at exciting possibilities for the future of gaming graphics.
FSR 4.1 Leak Via Proton Experimental
The recent discovery came to light when Valve released an early build of FSR 4.1 through the Proton Experimental channel. Although the file was swiftly removed after being spotted, a vigilant user managed to download it before it was taken down.
The Reddit user u/AtheleteDependent926 provided insights into the leaked “amdxcffx64.dll” file, revealing its potential for gaming applications. Through OptiScaler testing, it was confirmed that FSR 4.1.1 is compatible with RDNA 3.5 GPUs, including the RX 7800 XT, which is slated to officially support FSR 4.1 in the coming months. Surprisingly, even the previous generation RX 6900 XT based on RDNA 2 architecture demonstrated compatibility with the new FSR 4.1 model.
Implementing FSR 4.1 Support Through OptiScaler
To enable FSR 4.1 on previous-gen AMD Radeon GPUs, users can utilize OptiScaler by following a simple process. By updating the amd_fidelityfx_upscaler_dx12.dll file and enabling FSR4Update in OptiScaler.ini, gamers can unlock the potential of FSR 4.1 on their systems.
While AMD is still working on bringing FSR 4.1 to RDNA 2 GPUs, early testing has revealed visual artifacts on the RX 6900 XT. However, the leak suggests that the FSR 4.1 model performs optimally on RDNA 3.5-based graphics, despite AMD’s official silence on FSR 4 support for this architecture.
Conclusion
The leaked FSR 4.1.1 INT8 has opened up new possibilities for gaming enthusiasts, showcasing its compatibility with RDNA 3.5 architecture. While official announcements from AMD are awaited, the leaked version has already demonstrated promising results on various GPUs, hinting at a bright future for graphics technology.
