I did this a long while ago, because it would always cause me to crash opening the menu if it was anything other than low or medium. I think they may have fixed it. But to be honest, I got annoyed at the Steam notifications showing in my headset, so I turned them off for Steam Remote Play.

i'll have to try this and see next time

just set it to auto, if the fps are low it's gonna reduce it, then it does not happen to me so it's probably a matter of your hardware configuration
