make_launcher.py --dlssg needed --streamline, a Streamline SDK folder unpacked by hand, and make_kit.py could not carry DLSS Frame Generation at all, so a game built from the kit always left it off. tools/streamline_pin.py now pins the Streamline 2.14.16 SDK release (its archive's size and SHA-256, and the SHA-256 of each file the game loads): without --streamline the scripts download the archive once, check it, keep only sl.interposer.dll, sl.common.dll, sl.dlss_g.dll, sl.pcl.dll, sl.reflex.dll, nvngx_dlssg.dll and the two licence texts, each checked, and delete the archive. A folder given with --streamline must hold the pinned files. The bin/dlssg/ assembly moves from make_launcher.py into streamline_pin.place, so the release and the kit write the same set and the same dlssg-NOTICE.txt: a kit made with --dlssg and the 0.6.0 release's nx2navi_dlssg.dll has a bin/dlssg/ identical to the 0.6.0 release's, byte for byte. make_kit.py takes --dlssg [--streamline] like the launcher. nx2navi_dlssg.dll itself still comes from tools/build_dlssg.py. tests/launcher_test.py test_streamline_pin covers the extraction, the cache, refused archives and folders, and the notice.

"""Build nx2navi_dlssg.dll (runtime/dlssg/nx2_sl.cpp, DLSS Frame Generation through NVIDIA Streamline) with MSVC.
|
|
|
|
python tools/build_dlssg.py --sl <Streamline SDK folder with include/> [--out build/dlssg]
|
|
|
|
Streamline's C++ types have MSVC's ABI, so this one DLL is built with Visual Studio's compiler (the Build Tools are
|
|
enough; vswhere finds them), against the SDK's headers, which stay where they are. The Vulkan headers are MSYS2's.
|
|
A launcher release and the build kit ship the DLL ready-made beside Streamline's own runtime DLLs
|
|
(tools/make_launcher.py and tools/make_kit.py --dlssg, with the Streamline files tools/streamline_pin.py pins), and
|
|
tools/make_game.py place_dlssg puts them beside the game.
