Workaround Fix for Crash with DLSS

We're aware that some users face systematic crashes when using DLSS and we're sorry for that.

Here is a workaround to fix this by replacing some dll files :

  1. First, be sure to do a backup of the following folder elsewhere juste in case

  2. C:\\Program Files (x86)\\Steam\\steamapps\\common\\Aphelion\\Engine\\Plugins\\NvidiaDLSS\\Plugins

  3. Dowload the following zip file : https://developer.nvidia.com/downloads/assets/gameworks/downloads/secure/dlss/2026.05.21_ue5.5_dlss4.5plugin_v8.6.1.zip

  4. Extract the zip file then go to the "Plugins" folder

  5. Copy the "DLSS" and "StreamlineCore" folders

  6. Paste them in the following location :

  7. C:\\Program Files (x86)\\Steam\\steamapps\\common\\Aphelion\\Engine\\Plugins\\NvidiaDLSS\\Plugins
