  "description_en": "An FSR 4.1.1 INT8 investigation reconstructs the upscaler’s GPU passes in HLSL and compares their outputs with AMD’s compiled kernels through a D3D12 harness. The author reports byte-identical offline results for the documented passes and supplies an FFX-compatible provider build that obtains network weights from a user-supplied official DLL. Colour-mode paths and live frames have narrower comparison evidence.",
