I asked Muse how to Enable FSR in Unity URP, and its response was that FSR is not supported in Unity and that I should check if there’s a pack for it in the package manager. Which is wrong, Unity supports FSR 1.0 in URP 14.7…
I asked it few days later and it still doesn’t know FSR already exist in both URP and HDRP, FSR 1.0 in URP, and FSR 2.2 (I think) in HDRP, instead it told me to download some non existent FSR package from the web.
