适用场景

适用于在 AMD RDNA 1 及以上 GPU 上运行 Direct3D 12 游戏，希望使用 DLSS 质量模式（包括 DLAA 到超级性能）的用户。

查看 README 依据

# HelixSR **NVIDIA's DLSS Model E neural upscaler for AMD GPUs.** HelixSR runs NVIDIA's DLSS Model E network as standard Direct3D 12 compute shaders, **without NVIDIA Tensor Cores, an NVIDIA driver, CUDA, or ROCm**. It behaves like DLSS: no sharpening, every quality mode from native (DLAA) to Ultra Performance, dynamic resolution. The goal is to help gamers get better image quality from the hardware they already own, particularly older and lower-end GPUs. HelixSR is an independent, unofficial project and is **not affiliated with or endorsed by NVIDIA, AMD or the OptiScaler project**.

**Version 1.7.0.** For AMD RDNA 1 and newer GPUs, on Linux (Proton) and Windows. Developed and tested on the AMD BC-250 (gfx1013, Linux, Mesa RADV); other GPUs and Windows are not tested by us. **If 1.7.0 does not work for you, use [HelixSR 1.4.3](https://github.com/lonewolf0622/HelixSR/releases/tag/v1.4.3)** (and please open an issue with `helixsr.log`). ## Install 1. Download `HelixSR-1.7.0.zip` and extract it into a folder you keep (for example `C:\HelixSR` or your home folder). 2. Run the setup in that folder: - **Windows:** double-click `helixsr-setup.bat`

目标用户

面向游戏玩家，特别是使用老旧或低端 GPU 的用户。

使用方式

通过运行设置脚本安装到 Steam 游戏中，游戏内选择 DLSS 或 AMD FSR 作为升频器。非 Steam 游戏可通过手动安装方式。

查看 README 依据

- **Linux / Steam Deck:** `./helixsr-setup.sh` (in a terminal, or double-click and choose *Run in terminal*) 3. The first time, it asks to download NVIDIA's DLSS DLL (press Enter) and builds HelixSR's network from it (about a minute). 4. It then lists your Steam games and asks for each one: *install HelixSR? [Y/n]*. Close your games first. 5. Start the game and select the upscaler the setup told you: **DLSS** for games that have DLSS, **AMD FSR** for games that only have FSR. No launch options, no settings files.

| The game has | What the setup does | Select in the game | |---|---|---| | **DLSS** (or XeSS / FSR 2) | Installs the official [OptiScaler](https://github.com/OptiScaler/OptiScaler) 0.9.4 next to the game's `.exe` and points its FSR 3.1 backend at HelixSR (a `HelixSR` folder next to it). The game's DLSS inputs reach HelixSR. | **DLSS** | | **only FSR 3.1** | Replaces the game's FSR 3.1 DLL with HelixSR, as in 1.4.3; the game's file is kept as `*.original.dll`. No OptiScaler. | **AMD FSR** |

Everything the setup replaces is kept: in the game's `HelixSR\backup` folder (OptiScaler way) or as `*.original.dll`. **A game that is not listed** (not from Steam, or not detected): see `manual-install\README.txt`, which the setup creates. It has the files and steps for both ways. **Updating HelixSR:** extract the new version into a new folder, run its setup and answer yes to update your games. ## Switching between HelixSR and AMD FSR / FSR 4 In games installed the OptiScaler way (games with DLSS): 1. In the game, press **Insert** to open OptiScaler's menu.

部署要求

需要 AMD RDNA 1 或更新 GPU，支持 Linux (Proton) 和 Windows。Linux 需要 Python 3 和 numpy，Windows 首次运行会下载 Python、numpy 和着色器编译器。

**Version 1.7.0.** For AMD RDNA 1 and newer GPUs, on Linux (Proton) and Windows. Developed and tested on the AMD BC-250 (gfx1013, Linux, Mesa RADV); other GPUs and Windows are not tested by us. **If 1.7.0 does not work for you, use [HelixSR 1.4.3](https://github.com/lonewolf0622/HelixSR/releases/tag/v1.4.3)** (and please open an issue with `helixsr.log`). ## Install 1. Download `HelixSR-1.7.0.zip` and extract it into a folder you keep (for example `C:\HelixSR` or your home folder). 2. Run the setup in that folder: - **Windows:** double-click `helixsr-setup.bat`

- The setup downloads NVIDIA's DLSS 310.7.0 DLL from NVIDIA's GitHub ([github.com/NVIDIA/DLSS](https://github.com/NVIDIA/DLSS), NVIDIA's license applies) after asking, builds the network for your GPU (RDNA 3 and newer get extra 64-lane shaders; `--wave64` builds those too) into `helixsr_weights.bin` and `helixsr_kernels.pak`, and deletes NVIDIA's DLL again. Already have DLSS 310.7.0 (or 310.2) from a game? `--dlss <path to nvngx_dlss.dll>`. - **Windows:** Python, numpy and the shader compiler are downloaded once into `%LOCALAPPDATA%\HelixSR`. No admin rights.

- **Linux:** needs Python 3 with numpy (the setup uses your system's, offers to install them, or downloads a portable Python into `~/.local/share/HelixSR` on read-only systems such as SteamOS and Bazzite). The shader compiler runs through Proton. - Every download is pinned to an exact version and checked by SHA-256. - **`helixsr_weights.bin` and `helixsr_kernels.pak` contain NVIDIA's network: they are for your own PC, do not share or upload them.** ## How it works

已知限制

仅支持 Direct3D 12 游戏，不支持 Vega GPU（无 wave32）。不包含帧生成功能，但可配合 FSR 帧生成使用。

查看 README 依据

- Direct3D 12 games only. Only super resolution, no frame generation of its own. FSR frame generation (the game's, or OptiScaler's) keeps working: the setup puts AMD's frame generation DLL next to HelixSR. - AMD RDNA 1 and newer. Radeon Vega GPUs (Vega 56/64, Radeon VII, Vega graphics in Ryzen APUs) are not supported: they have no wave32. - Steam games are found automatically; other games through `manual-install`. ## License and legal
