The PC version of Hogwarts Legacy has seen many reports of constant stuttering and FPS drops. If our initial fix didn’t work for you, you might want to update your game, as Avalanche Software recently released its first performance patch for PC and Xbox since the global release.
However, if none of that works and you’re still suffering from issues, there’s one more thing you can do to ensure your game runs as smoothly as possible. Hogwarts Legacy uses an old NVIDIA DLSS file by default, and you must replace it with the updated version of the DLSS file.
You can either do it automatically using the DLSS swapper or manually do it yourself. The manual method is not too difficult either, as it is a simple file replacement in a particular folder. Here’s how you can update your Hogwarts Legacy DLSS file. Note that this solution will not work for AMD GPUs.
- Go to C:Program FilesSteamsteamappscommonHogwarts LegacyEnginePluginsRuntimeNvidiaDLSSBinariesThirdPartyWin64
- Make a backup of the existing nvngx_dlss.dll file inside this folder if you run into any issues. However, after multiple tests, it is highly unlikely you will face any issues.
- Go to this website and download the latest version of the DLSS.
- Copy the download nvngx_dlss.dll file into the folder and replace the old nvngx_dlss.dll file (which should now be renamed to nvngx_dlss.dll.bak).
