Game update

Nuclear Nightmare V4.1

Nuclear Nightmare · published 20 Sep 2025, 13:43 UTC · build 20059579

All newsPlayers around this dateRead on Steam

Patch Notes:
- Disable Slug Queen world setting option
- DLSS added back + FSR removed (fixes many different graphical errors and GPU crashes)
- NIS added: NIS is a image upscaler that can increase performance, by default will be turned off but you can toggle the NIS mode in the settings (only available on Nvidia cards)
- Area of Tower Island that caused players to fall through the map fixed
- Reduced level streaming stutters

Sorry everyone, FSR caused many graphical errors, crashes, and instabilities. During our testing on 6 different computers ranging in specs we did not see any of these errors/bugs, it wasn't until the update released that I saw the amount of problems it caused. I will try to look into implementing FSR in the future for AMD cards but at the moment it is too unstable.
