Steps to reproduce:
1. Open the attached “IN-149025” project
2. Open "Assets/OutdoorsScene.unity" scene
3. Press space twice to activate DLSS
4. Press left shift twice. Observe the quality changes and ScalableBufferManager.widthScaleFactor logs 0.35 and 0.7 depending on Ultra Performance or Maximum Quality
5. Press space again to switch to FSR2 and left shift twice
6. Observe the quality changes in the inspector
Actual result: Changing FSR2 mode does not change the internal resolution - the value returned by ScalableBufferManager.widthScaleFactor does not change and remains at 1
Expected result: Changing FSR mode changes the internal resolution
Reproducible with: 6000.0.0f1, 6000.0.80f1, 6000.3.20f1, 6000.5.5f1, 6000.6.0b5, 6000.7.0a3
Reproducible on: Windows 11

Workaround: Set FSR resolution manually
