gameDepthFormat now admits VK_FORMAT_R32_UINT alongside the existing
float/UNORM depth formats. The RR engine's hardwareDepth path
(DLSS.Use.HW.Depth) already handles the nonlinear interpretation;
the format check was the only gate keeping the feature on the CUDA
fallback.
Fixes Cyberpunk 2077 with RR enabled falling back to the CUDA path.
Native Vulkan NGX callers now get d4r's own network for presets K, M and L,
recorded straight into the caller's command buffer on the game's VkDevice with
the same GameUpscaler/GameUpscalerM adapters the D3D12 path uses through
vkd3d-proton. No CPU staging, CUDA evaluation or host wait. D4R_VULKAN_ENGINE=0
keeps the staging path, and anything the engine does not cover still goes there
with a logged reason.
- Inputs are sampled through the caller's views (SHADER_READ_ONLY_OPTIMAL, or
GENERAL with D4R_VULKAN_INPUT_GENERAL=1); depth/stencil views get a depth-only
view. The output must be an RGBA16F (or RGB10A2 with an RGB10 model) storage
image the engine writes directly, since the resource contract gives STORAGE
usage only.
- Every recording ends with an event; engine objects of a released feature are
destroyed once all recorded events fired, or at shutdown.
- GetFeatureDeviceExtensionRequirements reports VK_KHR_cooperative_matrix and
VK_EXT_shader_float8 where available. It applies d4r.ini first: games ask
before NGX init, and engine_requested() would otherwise cache "off".
- The engine accepts R16G16_SNORM motion vectors (Enshrouded).
- Engine model loaders accept a native device (VulkanInterop::native).
- Harness: D4R_HARNESS_ENGINE_DEVICE=1 (1.3 device with the engine's
features), D4R_HARNESS_ALLOW_BLACK=1 (staging K's black reset frame).
Harness vs the staging path (RX 9070, GE-Proton11-7, 640x360 -> 1280x720):
K 99.6 % bit-identical, rest within one half-float ulp; M 52.7 dB, L 54.3 dB
PSNR; dynamic, recreate and discard pass for K and M. In game, Enshrouded runs
preset M on this path (docs/vulkan.md, SUPPORTED_GAMES.md).

- engine/rr: d4r's own shaders for the denoiser frame (exposure, six encoders,
five decoders, hkpn output stage) at NGX layouts, plus PTX->GLSL/HIP packing
scripts, reference implementations and weight extraction
- runtime.h/runtime_rr.inc, game_rr.{h,cpp}: GameDenoiser wired into the engine
build (d4r-rr replay binary) and the D3D12 shim's feature-13 path
- shim: answer GetFeatureRequirements from d4r's own state only (the old
cross-binary CUDA handoff crashed OptiScaler's scan); drop the core's
CUDA GetFeatureRequirements import
- shim/harness: exact guide capture/replay of a frame's RR inputs
- kernels/rr: expanded enc0/engine prototypes; kernels/tools: ptxsim rewrite
plus rrsim and an engine test; vulkan: ptx2glsl FP8/cooperative-matrix
support, kvk inout buffers and KVK_DISABLE_OPTIMIZATION
- bridge: report the surface array in cuSurfObjectCreate traces
- packaging: RR settings and the ICU launch overrides in D4R_README
A standalone Vulkan inference engine (engine/) for DLSS presets K and M that
runs from weights extracted from the user's own nvngx_dlss.dll, with d4r's
own input, network and reconstruction shaders or the native HIP network
layers, recorded into the game's command list by the shim. Opt-in
([Engine] Enabled / D4R_ENGINE=1); anything uncovered falls back to the
CUDA/ZLUDA path with the reason logged.
Byte-identical to NGX's CUDA backend under the phase-capable reference
(1706x960 -> 2560x1440, native HIP network, eleven frames, RX 9070 XT):
- K render- and display-resolution motion vectors, HDR and LDR
- K game-supplied exposure and automatic exposure with any pre-exposure
and exposure scale (one residual: effective exposure exactly 2 or 4)
- K and M with the DLSS indicator's inverted-axis parameters
- M with any exposure settings (NGX ignores them for M)
K packages need the current compile_k.py (marker D4RO0003).
Also: HIP shared buffers are pooled across feature recreation (ROCm leaks
destroyed imports), hipnet.bin must match the preset, M-only games do not
load the K model, install_d4r_runtime.sh stages k, k-ldr, m, m-ldr with
hip/, the activation table has a generator (gen_activation_m.py), and
package_release.sh can bundle the engine's shaders (never its weights).
