I created an empty C++ project, added the 5.7.0 plugin to its Plugins folder, opened its visual studio project and ran the build process, but that fails with errors. Is this just not compatible at all? Do we have to wait on AMD to release a new plugin?
Still having no luck. I’ve got my project working with Visual Studio 2026, but all attempts to compile the FSR plugin result in the following.
Plugin 'FSR' failed to load because module 'FFXFSRSettings' could not be found. Please ensure the plugin is properly installed, otherwise consider disabling the plugin for this project.
Does anyone have any suggestions here? I’ve already tried moving it to the Plugins/Markplace folder of the engine as well. It outputs the same error.
Ok, rebuilt the entire project from within Visual Studio 2026 and extracted the compile log. Looks like there’s a lot more to it. Plugin itself seams to need several code fixes to be compatible with 5.8. Below is the log.

May give fixing some of this a try, but it at least explains why AMD is taking forever to update the plugin. DLSS and XeSS have already released UE5.8 plugins.
Hello there @Krileon!
Indeed, the FSR plugin won’t work with 5.8, at least for the moment, as AMD as yet to release an update for the component:
Manual fixing would be possible, but we are talking about a big chung of custom C++ code. I would suggest waiting for the official update instead, which can be checked on their site:
For the moment, the alternatives are to stay on 5.7, or work with 5.8 using UE’s own TSR:
Thanks ChatGPT.
I’m aware of all of that. That’s pretty obvious from my topic. I’m opening discussion here to try and fix this without having to wait months for AMD to do something about it.
