For RTX 2000 and up users only unfortunately.
What, why and how?
What?
DLSS (Deep Learning Super Sampling) is NVIDIA’s AI tech that boosts game performance by upscaling lower-resolution graphics to look high-quality, improving frame rates and visuals.
With the recent Cyberpunk 2077 update, we got access to the new and improved DLSS 4.0 files.
Why?
For a roughly 5-10% FPS impact we can enjoy a more stable, detailed image while also providing better Anti-Aliasing.
Or get more FPS without losing quality, by choosing a lower base resolution (more upscaling).
How?
DLL swapping involves replacing a game’s DLSS DLL file with a different version to improve performance or visuals.
To do that, you need to:
1. Locate your “nvngx_dlss.dll” file in your games directory.
Most likely here: \SteamLibrary\steamapps\common\Cities Skylines II
2. Now get the new DLL.
A) If you have Cyberpunk, you can take it straight from the source.
B) If not- you can refer to this reddit post with a download link.
Mandatory “Never trust download links lecture”, but I’ve compared the files with the ones from Cyberpunk - They’re identical (SHA256 of ad3e9c07ee864e9702032459a59c6825166766c2cb75bd0318d5626595693bdb)
3. Backup your original DLL file and replace it with the new one.
4. Obviously enable DLSS in the game settings.
Cheers!
