RDNA2 has native kernels for K's layers only; L's and M's test frames still
compiled their transformer layers with emulated matrix products for most of
an hour. The builder now builds e, f, k, k-ldr on gfx103x (detected like the
native kernels: D4R_GPU_ARCH, else the KFD node with the most SIMDs);
D4R_ENGINE_ALL_MODELS=1 builds L and M anyway. install.sh takes the model
list from build-engine-models.sh --list-sr-models and keys the shared cache
on it.
Models build in alphabetical order (E, F, K, L, M). The first frame renders
alone to create the Proton prefix; the rest render at the same time, each
model built as soon as its frame is done (ZLUDA compiles in one thread per
process). Cold install.sh --yes on a Steam Deck: 185 s.
The models list and its completeness check (have) only knew rr-* and
k/m/l: an up-to-date stamp skipped the builder, so engine\e and engine\f
(the DLSS 3 CNN, the RDNA2 route) were never built on installs that
already had the other models, and copy_models skipped them from the
shared cache. The prompt now names the RDNA2 route.
- Add native preset K kernels for gfx1030–gfx1036 using software matrix
products, with fast and accuracy builds and RDNA2 motion kernels.
- Follow OptiScaler's DLSS and RR preset overrides, sanitize unsupported
values and select the preset matching the feature's quality mode.
- Enable FSR 4 under NVIDIA GPU spoofing by exposing real AMD PCI IDs
to OptiScaler and FidelityFX modules; bundle AMD's loader and upscaler.
- Keep K on native kernels in engine auto mode unless HIP is selected,
and fall back to CUDA for M/L when shader_float8 is unavailable.
- Add native-engine K GPU timings, preset recreation harness controls
and regression coverage; fix the input-wait test's glibc name clash.
- Update configuration, installer guidance and release documentation,
simplify the README and move gameplay videos to docs/videos.md.
RDNA2 kernels remain untested on RDNA2 hardware; software matrix
arithmetic was validated against WMMA on RDNA3.
ask() takes the default on Enter or EOF, ignores whitespace, accepts any answer starting with y or n and
re-asks otherwise. Without a terminal (or with --yes) DO_ENGINE defaults to building the models.
RELEASE_NOTES.md: the install.sh engine setup, [Engine] Enabled = auto, and the FSR Ray Regeneration backend
that this build does not carry.
Verified copies go to ~/.cache/d4r: the next game's install copies them instead of downloading or building
again. Enabled = auto (the new default) turns the engine on when d4r/engine holds a model; the shim probes the
nine model folders. build-engine-models.sh gains --exact (NVIDIA's roundings) and --find-proton.
A fresh extract plus bash install.sh builds all 9 models in about a minute, and they run in the shim.
Engine-vs-CUDA path: K 67 dB, M/L 45-50 dB, RR D/E/F 43/46/37 dB.
Add an optional D4R_INSTALL_MODE=asi release (d4r-<version>-asi.zip)
holding only d4r.asi and a companion d4r/ folder, to drop into an
existing OptiScaler plugin directory.
- Shim: export InitializeASI. It identifies OptiScaler by its PE export
name to find the active INI, then launches d4r-setup.exe out of
process (no GPU or network work under the loader lock). The .asi
build loads its runtime and config from the companion d4r/ folder.
- tools/d4r_asi_setup.cpp: native helper. It waits for the game to
exit, installs the D3D12 wrapper and the private d4r12core.dll beside
the EXE, and merges the NGX route into the loader's INI (including
GE-Proton's prefix-local INI) with backups. Unchanged launches do
nothing. It skips Proton helpers and background utilities and runs
setup for one plugin install at a time.
- scripts/private_d3d12_core.py: points vkd3d's d3d12.dll forwarder at
d4r12core.dll without moving code addresses.
- install.sh runs from inside the ASI's d4r/ as well as the proxy
release root. d4r-check.sh checks ASI installs (loader, plugin path,
LoadAsiPlugins, HookOriginalNvngxOnly, Wine drive paths).
- Packaging, build script, docs, ASI_README.txt and tests.
