- Add docs/in-place-inputs.md: reading the DLSS inputs in place does not work, because a hardware texture fetch on a HIP texture object over memory imported from vkd3d-proton returns stale data while plain loads and cuMemcpy2D are correct; records the measurements, the rule-outs and the reworked-fetch workaround that turned out not to pay for itself. - Add tools/hip_vk_texture_stale_repro.cpp and its build script, the native Vulkan + HIP reproducer that rules out a general ROCm or RADV bug.
