KARDS - The WW2 Card Game: Steam Deck OLED Settings

To achieve the best balance of visual responsiveness and battery life in KARDS - The WW2 Card Game on the Steam Deck OLED running SteamOS 3.7.17, set a 60 FPS frame rate limit in SteamOS and run the game at native 1280x800 resolution. A 60 FPS cap preserves smooth animations during card deployments and frontline movements while yielding roughly 5 to 6 hours of playtime. If you need maximum battery life away from a power outlet, drop the cap to 30 FPS to gain up to 7 to 8 hours of battery runtime at the expense of animation fluidity.

Frame Rate Limit Comparison

Running KARDS - The WW2 Card Game without an FPS cap pushes the APU toward the OLED display's 90Hz limit, drawing unnecessary power during card dragging, unit combat, and order animations. Because KARDS is a turn-based tactical card game, frame rates above 60 FPS offer no gameplay advantage and drain the 50Wh battery in roughly 3 to 3.5 hours.

Performance Mode	Frame Rate Limit	Estimated Battery Life	Animation Quality	Best Use Case
Balanced (Recommended)	60 FPS	~5–6 hours	Smooth and responsive	Standard ranked play, ladder climbing, docked or handheld
Endurance	30 FPS	~7–8 hours	Noticeable judder	Commutes, flights, low-battery situations
Uncapped	Off (up to 90 FPS)	~3–3.5 hours	Highest fluidity	Benchmarking only; not recommended for normal play

The 60 FPS profile keeps trackpad and touchscreen card targeting snappy while maintaining cool, quiet operation. The 30 FPS cap introduces visible judder when dragging cards across the support line or inspecting the collection album, but turn timers, combat resolution, and tactical decisions remain fully functional.

In-Game Display Settings

The main menu, deck builder, and card collection screens contain animated visual effects and 3D card inspect shaders that draw steady system power. Align the in-game display settings with the Steam Deck hardware to prevent scaling blur and excessive rendering load:

Resolution: 1280x800 (matches the native 16:10 aspect ratio and prevents letterboxing)
Window Mode: Fullscreen or Borderless Fullscreen (allows SteamOS Gamescope to manage frame pacing properly)
V-Sync: Enabled in-game or handled via the SteamOS frame limiter to eliminate tearing during rapid card flips
Quality Settings: Balanced graphical presets to keep card text and unit stats sharp without overtaxing the GPU on static art

How to Configure the SteamOS Performance Profile

Apply these adjustments through a per-game profile so your settings load automatically whenever you launch the game:

Press the Quick Access Menu button (...) on the right side of the Steam Deck OLED.
Select the Performance tab (the battery icon).
Turn on Use per-game profile.
Set the Frame Rate Limit slider to 60 FPS for balanced daily play, or 30 FPS for travel endurance.
Set the scaling filter to Linear or Auto, since the native 1280x800 in-game resolution avoids scaling artifacts.
Close the Quick Access Menu to apply the settings to your active session.
