Based on what you’ve described:
-
FFXFSR3Settings Error: This usually happens when the module isn’t properly linked or the plugin isn’t compatible with the new engine version. Have you tried manually regenerating the Visual Studio project files and rebuilding the solution after adding the plugin? Sometimes this step resolves module-related errors.
-
Recompiling for 5.5.1: Since the build.sh reflects both private
.cpp
and public.h
files, it might help to verify if the plugin files have the correct directory structure and if theBuild.cs
file is updated to support UE 5.5.1. Updating theEngineVersion
in the.uplugin
file to match 5.5.1 might also help. -
Getting FSR Back: If you’ve already set up custom settings, you might want to temporarily revert to 5.4 to export the plugin settings, or manually carry over those configurations while troubleshooting compatibility.
Have you checked any unofficial repositories or modded versions of FSR? Sometimes, community-maintained patches keep pace with engine updates. Let me know if you find a solution!
I’m also trying to make DLSS, FSR, and XeSS work smoothly with 5.5.1, so I’ll update.
