Nightingale, a survival simulator, was originally planned to be released with support for Intel XeSS, NVIDIA DLSS 3 and AMD FSR3.
Due to technical issues discovered during the server stress test, AMD support FSR3 was removed from the release version. The AMD FSR3 integration caused a significant number of bugs. The developers are collaborating with external teams to resolve issues and re-integrate FSR3 in the future.
The developers recommended using frame generation technologies to improve productivity, said to be up to 80%. The release version is expected to support NVIDIA DLSS.
Perhaps the developers will add AMD FSR2 until the problems with FSR3 are fixed.
