Shadow Quality vs Texture Quality
Our pick: Shadow Quality
Lowering shadows provides a bigger performance boost than textures in this specific engine.

Minimalist tension that sips battery.
ROG Ally Z1 Extreme · Ally X · ROG Xbox Ally X
The short answer
Casualties: Unknown performs exceptionally well on the Ally, but you must address the lack of native controller support first. You can easily hold a locked 60 FPS at 1080p using just 12-15W in Manual mode, giving you hours of battery life. The biggest hurdle is mapping the controls; you must enable Steam Input and grab a community layout because the game expects a keyboard and mouse. Once that is sorted, the experience is flawless. It is a great pick for when you are away from a charger.

Extra tuning
Shared memory. This model shares 24GB between Windows and graphics. Extra memory gives textures more room, so raise textures before anything else. Change allocation only if the game needs it.
120Hz & VRR. Keep the built-in display at 120Hz for VRR. Below its native VRR range, low-framerate compensation can help; a 40 FPS cap keeps cursor movement and menu scrolling responsive.
Power & cooling. TDP is APU power, not the whole handheld’s draw. The battery range below includes display and system overhead.

Start with the listed settings, then check a demanding scene before raising detail. Keep frame generation separate from the underlying frame rate when judging input response.
Shadow Quality vs Texture Quality
Lowering shadows provides a bigger performance boost than textures in this specific engine.
Post-Processing vs Resolution
Disabling post-processing preserves the sharp native 1080p look while reducing GPU load.
The reality check
The original Ally has 16GB shared memory and a 40Wh battery. Ally X and Xbox Ally X have 24GB and 80Wh. The extra memory gives textures more room and the bigger battery doubles session length, while the same settings profile holds across all three models.
Away from the charger
Couch mode · 15W APU power
Use 25W with a charger nearby. Keep vents clear and establish a steady frame cap before raising resolution.
Try the 12W road-trip profile and lower resolution first. If heavy simulation turns in Casualties: Unknown cannot hold the cap, use the couch profile instead of accepting uneven response.

Uses 90% of battery capacity and 8-12W for the display and other system power. Brightness, battery wear, background apps and actual game load change runtime; TDP alone is not total power draw.
Pack & play
to Esc and Tab
Right rear button
Your right thumb stays free for the cursor and quick menu jumps.
Assign one action per rear button in the game’s Armoury Crate profile. Keep the default face buttons available and avoid repeated-input macros in online play.
Offline availability depends on the game and its launcher.
What to pay attention to on a handheld.
The game is generally very light, but expect minor frame time variance when entering rooms with complex dynamic lighting or multiple interactable objects.
UI elements and text logs are very clean; keep the resolution at 1080p to ensure the minimalist interface remains perfectly sharp on the 7 inch screen.
Because the game draws so little power, you can run the fans on a very quiet curve in Manual mode without thermal throttling.
Shaders compile almost instantly on the Z1 Extreme, so you will not see the stuttering typical of more complex 3D titles.
Enable Steam Input in the game properties and pick a community layout that maps the sticks to mouse movement.
This title uses borderless windowed mode only; if it starts behind other windows, use Alt+Tab or the Task View button.
There is no Steam Cloud support, so you must manually copy settings.json from the AppData folder if you switch handhelds.
The screen can stay at 120Hz for VRR, but the game engine is most stable with a 60 FPS cap.
Yes, the game is DRM-free and does not require an active internet connection to launch.
No, the UI is very clean and the 1080p resolution keeps every log and menu item sharp.
