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 :
First, be sure to do a backup of the following folder elsewhere juste in case
C:\\Program Files (x86)\\Steam\\steamapps\\common\\Aphelion\\Engine\\Plugins\\NvidiaDLSS\\Plugins
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
Extract the zip file then go to the "Plugins" folder
Copy the "DLSS" and "StreamlineCore" folders
Paste them in the following location :
C:\\Program Files (x86)\\Steam\\steamapps\\common\\Aphelion\\Engine\\Plugins\\NvidiaDLSS\\Plugins
