HelixSR 1.8.1: setup fixes, and an experimental way to use the game's own DLSS option without OptiScaler.

Install: extract the zip, run helixsr-setup.bat (Windows) or helixsr-setup.sh (Linux) and press Enter. For each game it asks install? [f/o/n]: f = FSR (pick AMD FSR in the game), o = OptiScaler (pick DLSS in the game), n = skip. Enter takes the first letter. At the end it lists what to pick in each game.

What changed since 1.8.0

• Setup: answers are confirmed right away. After f / o the setup now says what it will do ("-> FSR, installed after the last question"). A letter that is not offered gets a short hint instead of the same question again.
• Setup: no more double entries. A game folder dropped onto the setup (or dragged in at "Another game?") that belongs to a game already in the list is not listed a second time. A folder inside a game (for example its Binaries\Win64) now finds the game's FSR DLL, so f is offered for it.
• Setup: a missing OptiScaler.ini next to a game no longer stops the setup (a new one is made), and install N / uninstall N from the command line work again.
• New, EXPERIMENTAL: d = DLSS without OptiScaler (games with DLSS). The setup puts HelixSR's DLSS loader (dxgi.dll) and HelixSR (as nvngx.dll) next to the game's .exe; the game's own DLSS option then runs HelixSR.

  Experimental: tested in very few games, on Linux (Proton) only, not tested on Windows. It may not work or may crash the game. Do not use it in online games or games with anti-cheat (ban risk). It is never the default; read the README section Experimental: DLSS without OptiScaler first. Switch back any time: run the setup and pick f or o.

• Wave size with the DLSS loader follows the real GPU (RDNA 3 and newer: 64-lane network shaders), not the NVIDIA GPU the game is shown. FSR and OptiScaler installs behave as in 1.8.0.

The HelixSR DLL is otherwise unchanged from 1.8.0 (same network, same speed).

Updating: extract 1.8.1 into a new folder, run its setup and press Enter for your games.

If 1.8.1 does not work for you, use HelixSR 1.4.3 and please open an issue with helixsr.log.

The download contains no NVIDIA weights or NVIDIA-derived kernels; the setup builds them on your PC from NVIDIA's DLSS DLL. After the setup, HelixSR's DLLs contain NVIDIA's network: they are for your own PC, do not share or upload them.
