Call of Duty Warzone 2.0 on the Steam Deck @ 50ish FPS

I am running Call of Duty Warzone 2.0 on the Steam Deck on Windows 11 with 50ish FPS at most times. The game is the Steam version and the Steam Deck controls are working natively. Aim assist works without issue as well. The video settings are default “minimal”, AMD FSR 1.0 set to “Performance”, and Vsync turned on (later in the video).

I have installed Windows to a partition on my main SSD on the Steam Deck. To get back to SteamOS I just simply have to reboot it and choose to boot Steam OS by holding down the volume down button.
