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]C:\\Program Files (x86)\\Steam\\steamapps\\common\\Aphelion\\Engine\\Plugins\\NvidiaDLSS\\Plugins[/c]

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]C:\\Program Files (x86)\\Steam\\steamapps\\common\\Aphelion\\Engine\\Plugins\\NvidiaDLSS\\Plugins[/c]

Watch the launch trailer: 

To celebrate, both the Standard and Deluxe Editions are 10% off for two weeks!

The Deluxe Edition – exclusive to Steam – contains the game, cosmetics pack, digital artbook, and OST by award-winning composer Amine Bouhafa (which you can get standalone if you want). The cosmetics pack has 2 spacesuit variants and 6 backpack accessories: 3 stickers and 3 keychains, referencing our collaboration with the European Space Agency and two of our other well-loved games, Jusant and Lost Records: Bloom & Rage.  

Aphelion is a cinematic action-adventure game set in space, blending exploration, traversal, stealth, and mystery. But more than anything, it’s a story-rich human journey. Play as Ariane and Thomas as they navigate this new and alien world in a desperate attempt to find one another after their crash-landing. 

We really hope you enjoy your experience on Persephone. 

“Ignition, and... lift off.” 

 P.S. To celebrate the launch of Aphelion, all DON’T NOD-published games are on sale tonight at 7PM CEST!
