dlssg-to-fsr3

**dlssg-to-fsr3** is a drop-in mod/replacement for games utilizing [Nvidia's DLSS-G Frame Generation](https://nvidianews.nvidia.com/news/nvidia-introduces-dlss-3-with-breakthrough-ai-powered-frame-generation-for-up-to-4x-performance) technology that allows people to use [AMD's FSR 3 Frame Generation](https://github.com/GPUOpen-LibrariesAndSDKs/FidelityFX-SDK) technology instead. Only RTX 1600, RTX 2000, and RTX 3000 series GPUs are supported. Game-specific compatibility can be [found here](https://github.com/Nukem9/dlssg-to-fsr3/wiki/Game-Compatibility-List). Using dlssg-to-fsr3 in multiplayer games is ill advised and may lead to account bans. **Use at your own risk.** ## Download Link [https://www.nexusmods.com/site/mods/738](https://www.nexusmods.com/site/mods/738?tab=files) ## Installation for Users Universal Method (Recommended)
1. Pick **one** of the included generic DLLs to use. Possible options are `version.dll`, `winhttp.dll`, or `dbghelp.dll`. We'll choose `version.dll` in this example. 2. Find your game's installation folder. For Hogwarts Legacy, this is the directory containing `HogwartsLegacy.exe`. An example path is `C:\Program Files (x86)\Steam\steamapps\common\Hogwarts Legacy\Phoenix\Binaries\Win64\`. 3. Copy `dlssg_to_fsr3_amd_is_better.dll` and `version.dll` to your game's installation folder. 4. Done. A log file named `dlssg_to_fsr3.log` will be created after you launch the game. NVNGX Method
1. Double click on `DisableNvidiaSignatureChecks.reg` and select **Run**. Click **Yes** on the next few dialogs. 2. Find your game's installation folder. For Cyberpunk 2077, this is the directory containing `Cyberpunk2077.exe`. An example path is `C:\Program Files (x86)\Steam\steamapps\common\Cyberpunk 2077\bin\x64\`. 3. Copy `dlssg_to_fsr3_amd_is_better.dll` and the new `nvngx.dll` to your game's installation folder. 4. A log file named `dlssg_to_fsr3.log` will be created after you launch the game. DLSSTweaks Method
1. Please see the [included readme](/resources/read_me_dlsstweaks.txt). ## Installation for Developers 1. Open `CMakeUserEnvVars.json` with a text editor and rename `___GAME_ROOT_DIRECTORY` to `GAME_ROOT_DIRECTORY`. 2. Change the path in `GAME_ROOT_DIRECTORY` to your game of choice. Built DLLs are automatically copied over. 3. Change the path in `GAME_DEBUGGER_CMDLINE` to your executable of choice. This allows direct debugging from Visual Studio's interface. 4. Manually copy `resources\dlssg_to_fsr3.ini` to the game directory for FSR 3 visualization and debug options. ## Building ### Requirements - This repository and all of its submodules cloned. - The [Vulkan SDK](https://vulkan.lunarg.com/) and `VULKAN_SDK` environment variable set. - **Visual Studio 2022** 17.9.6 or newer. - **CMake** 3.26 or newer. - **Vcpkg**. ### FidelityFX SDK 1.

Done. ### dlssg-to-fsr3 (Option 1, Visual Studio UI) 1. Open `CMakeLists.txt` directly or open the root folder containing `CMakeLists.txt`. 2. Select one of the preset configurations from the dropdown, e.g. `Universal Release x64`. 3. Build and wait for compilation. 4. Build files are written to the bin folder. Done. ### dlssg-to-fsr3 (Option 2, Powershell Script) 1. Open a Powershell command window. 2. Run `.\Make-Release.ps1` and wait for compilation. 3. Build files from each configuration are written to the bin folder and archived. Done. ## Changelog Click to expand.
