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.
