Can I Add DLSS to a Game That Doesn’t Natively Support It?

You might want to check out a thread about modding DLSS into games. Some people have had success with mods, like for Elden Ring, so it's worth looking into specific games to see if anyone has shared instructions or tools.

There are some games where you can put DLSS in if they already have support for technologies like FSR or Xess. If the game doesn’t have anything similar, it might be tougher to get DLSS working, but you could still find some guides to help you out.

Technically, it's not straightforward. If you're not particularly skilled with modding, doing it yourself can be quite challenging. However, if you look online, there might be guides or mods available for your specific game that could help! Another option is to try out Lossless Scaling, which might work for you!
