The next step is to provide additional virtual memory for the game to draw from and run smoother overall. You need at least 10GB of free space to use as virtual memory. Also remember to never fill your storage drive over 90% otherwise things will slow down and the storage drive will be affected. If you need to install a larger storage device in your Steam Deck, see this SSD replacement guide.
Let’s set up additional virtual memory. Open Windows File Explorer and navigate to the This PC icon, right-click the icon, and then select Properties to bring up these options. Next, go to “Advanced system settings” and open it. Click on the “Performance” tab and then on the next prompt “Settings”.

You can walk now war zone 2 and go to the in-game settings menu. This is quite a demanding game, but it’s possible to get a playable experience averaging 60 fps in certain areas. Most gamers don’t want frame rate drops, so we recommend using low (Basic) settings and AMD FSR upscaling in the highest quality mode. You can also set the texture resolution to low and the video memory scaling to 75.
You’ll get decent performance in with these settings Call of Duty: Warzone 2 on the Steam deck, but you have to keep in mind that the device has limited performance potential.
