Accidentally Leaked FSR 4.1.1 INT8 Reportedly Works With RDNA 3.5 Graphics
Wccftech • • technology
Key Points:
- Valve accidentally leaked an early build of FSR 4.1.1 INT8 through Proton Experimental, which was quickly removed but downloaded by a Reddit user.
- The leaked FSR 4.1.1 version works on RDNA 3 GPUs like the RX 7800 XT and surprisingly also on RDNA 2 GPUs such as the RX 6900 XT, though with some visual artifacts on the latter.
- The user demonstrated that by using OptiScaler and updating certain files, FSR 4.1 support can be enabled on previous-generation AMD Radeon GPUs.
- This leak suggests that FSR 4.1 may also support RDNA 3.5 architecture, including Radeon 890M iGPUs found in high-end Strix Point APUs, despite AMD's previous silence and conflicting reports.
- The community hopes AMD will officially extend FSR 4.1 support to RDNA 3.5, which is important for upcoming Zen 5-based APU families relying on this architecture.
