Just a heads up to anyone experiencing a crash upon loading their project with FSR enabled in editor. Unfortunately (and too late for me) I thought that my project was corrupted and deleted my config etc etc only to find out that the issue is that Unreal is unable to initialise the plugin under the new Adrenaline 25.5.1 Drivers. This causes unreal engine to crash with a DirectX driver stopped working error.
The issue is fixed when reverting to 25.4.1 or below.
Hopefully some of you see this before nuking a perfectly good project. Can’t find any way to log this with AMD so hopefully someone can let them know.
