dlaa and the DLSS modes need nvngx_dlss.dll next to totk.exe, which the release does not ship, so most players never had DLSS. A new setup step after prepare downloads NVIDIA's own copy from the DLSS SDK repository (github.com/NVIDIA/DLSS, tag v310.9.1, NVIDIA RTX SDK license) and checks its size and SHA-256. The window has a tick box for it, on by default and named with its source and licence; the CLI takes --dlss. The step runs on Windows with an NVIDIA RTX GPU (the host check's Vulkan devices), keeps a DLSS library the player already put there, and on a failed download warns and lets the game run without DLSS; the next setup run tries again. Texts in English, Russian, Brazilian Portuguese and Simplified Chinese, docs/installer.md step 7, tests in tests/installer_test.py (DlssTest, with a file: URL).

A first install needs every option. --firmware names the Switch firmware folder (an unpacked firmware or an emulator's
|
|
Contents/registered); the setup extracts the system shared fonts from it when the language is Chinese, Korean or
|
|
Traditional Chinese. On a folder with totk-install.json (resume after a cancel or failure, or update with a newer
|
|
release) only --dest is needed: --lang defaults to the recorded language, and the game files are needed only when the
|
|
extraction has to run again. Prints JSON events on stdout (events.py). Exit code: 0 done, 1 failed, 2 bad command
|
|
line, 3 cancelled (Ctrl+C or Ctrl+Break).
|
|
|
|
--dlss downloads NVIDIA's DLSS library (nvngx_dlss.dll) from NVIDIA's DLSS SDK repository into the install folder on
|
|
Windows with an NVIDIA RTX GPU (steps.py, Dlss).
