Presets E (5) and F (6) run on d4r's own Vulkan engine without cooperative
matrices: the input and reconstruction kernels translated from the user's DLL
(engine/compile_sr_e.py, rr/ptx2rr.py), the network engine/sr/e_net.comp with
packed v_pk_fma_f16 accumulation (engine/cnn_sr/mma_f16.glsl, the default
head; --head-accumulation f32 keeps the f32 head). Runtime runtime_e.inc
(EModel/EEngine), game adapter game_e.cpp, replay d4r-e; the shim serves them
from engine\e and engine\f (D4R_ENGINE_MODEL_E_DIR / _F_DIR), LDR or HDR, any
render size, not with AutoExposure. build-engine-models.sh builds both.
Translator fixes that apply to every translated kernel: .relu on f16/f16x2
fma/add/mul was ignored; add.rz was always taken for the roundf idiom (lost
the log1pf correction term); formatted image stores expand at the call site
(SPIR-V image type fix); f16 mma.sync m16n8k8/k16, .const loads, shared
16-bit stores, aligned 32-bit arena words (D4R_WORD_ARENA), unified arena.
Steam Deck gfx1033: 2.55 ms at 640x360 -> 1280x720, 6.20 ms at 1080p
output; Rounded Quality sizes take mid_3x3 (reconstruction 2.44 -> 1.23 ms).
Ray Reconstruction CNN presets A-C (compile_rr3.py, the packed RR flavor)
stay out of this commit; engine/README.md already documents their tuning.
- the weights go into the command buffer with vkCmdUpdateBuffer (recordContents); the host-visible staging
copies are gone, and the host copies are dropped once recorded
- an engine's own output image is created only for frames that do not write the caller's texture
(K, M, RR D/E, RR F), cleared on first use
- preset F: the tile slots share the arena with the network's regions, and the gather records' rows fill the
gaps between encoder 0's regions (rr.txt "s3", six words on enc0's block; D4R_ENGINE_RR_ARENA keeps the
old separate layout for arena dumps)
- the shim reserves the render size the feature was created with for the M/L Vulkan network instead of the
output size; a frame beyond it goes to a second, output-sized engine (1.1 GB less for M, 1.4 for L at
1280x720 -> 4K); replay_m gains D4R_M_CAPACITY
Every reference capture still byte-identical; through the shim the harness process peaks 159 MiB lower.
- 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).
