FSR 4.1.1 INT8 Emerges for RDNA 3.5 via Valve Leak
TL;DR Summary
Valve’s Proton Experimental leak hints that FSR 4.1.1 INT8 can run on RDNA 3.5 GPUs (including RX 7800 XT) and even RDNA 2 cards, using a workaround with a signed amdxcffx64.dll and OptiScaler to enable FSR4Update in OptiScaler.ini. The Radeon 890M iGPU reportedly works too, but AMD has not officially confirmed RDNA 3.5 support for FSR 4.1, and artifacts or instability may occur on some GPUs. This is a leak, not official release.
