Steps to reproduce:
1. Open the attached “IN-122612_FSR2Test (2) (2).zip“ project (link in the internal comments)
2. Open the “OutdoorsScene”
3. Enter Play mode
4. Press the left mouse button on the Game view to change the FSR Mode and ScaleFactor (while observing the text displayed in the Game view)

Expected result: The FSR Mode changes with each click to 1, 2, 3 and 0 (it wraps around), and the ScaleFactor (and resolution) change to “0.600x0.600” (2304x1296), “0.500x0.500” (1920x1080), “0.400x0.400” (1536x864), and “0.700x0.700” (2688x1512) accordingly
Actual result: The FSR Mode changes with each click to 1, 2, 3 and 0 (it wraps around), but the ScaleFactor (and resolution) remain unchanged at “0.700x0.700” (2688x1512)

Reproducible with: 6000.0.61f1, 6000.2.10f1, 6000.3.0b8, 6000.4.0a4

Reproduced on: Windows 11 Pro (25H2)
Not reproduced on: No other environment tested

Workaround:
1. Select the “Main Camera” GameObject in the Hierarchy
2. In the Inspector, enable the “Use FSR2 Custom Attributes” option under the “Camera” component > “Rendering” > “HDRP Dynamic Resolution” > “AMD FidelityFX Super Resolution 2.0 (FSR2)” (disabling the option again will bring the ScaleFactor (and resolution) back to the one set in the current HDRP asset)

Notes:
- Reproducible in the Player
- Could not test with URP (FSR 2 is not yet supported in URP)
- When setting the Quality Mode for FSR2 in the HDRP asset, the correct mode is applied but the “Camera” component’s override is ignored. If you change the Quality Mode in the “Camera” component’s dropdown, it has no effect on the Game view and it just uses the HDRP asset’s value
