Recommended NVFP4 hybrid — v0.7.2

Promotes the tested combined NVFP4 hybrid as the recommended Blackwell option. FP8 and the previous hybrid remain selectable.

At 2560x1440 model input, this uses split-half contraction with narrower scratch synchronization. At 3840x2160, it narrows pack/contraction synchronization; larger supported input retains the previous route. Uses the existing hybrid weights and includes both required candidate kernel/helper assets.

Validation: Release build passed; 13 prior production-source checks covered switching, fallback, moving scenes and cuts. All 51 packaged file hashes verified. In BG3, one 120-second capture per model with the first 20 seconds discarded measured 55.16 rendered FPS recommended, 54.91 previous hybrid, and 54.57 FP8. The recommended path had a slightly lower 1% low; these small average gains are not established as repeatable. The 1440p path introduces small rounding differences; tested 4K output is byte-identical to the previous hybrid.

Neural Rendering remains opt-in and the portable configuration retains FP8 for hardware compatibility. Select NVFP4 hybrid (recommended) on Blackwell. NVIDIA's NR runtime must still be supplied separately. Kingdom Come II compatibility testing is separate and is not claimed by this release.
