Resolution vs FPS
Our pick: Resolution
900p is the sweet spot for visual clarity without losing the 60 FPS target.

The short answer
Can Warhammer 40,000: Boltgun 2 run on ROG Ally?
Boltgun 2 is a dream on the Ally, holding a steady 60 FPS on the 15W Balanced profile at 900p with FSR set to Quality. I noticed that while the general exploration is light on the GPU, the Purge arena fights introduce heavy particle effects that can cause minor dips if your wattage is too low. To keep things locked, I recommend setting your VRAM to 6GB on the standard Ally and 8GB on the Ally X to handle the updated texture pools. If you want to push for the full 120Hz experience, bump the TDP to 25W and drop the resolution to 720p. It is a fantastic native Windows experience that feels significantly more responsive than the original game.

Extra tuning
ROG Ally X: hardware setup
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 aim and inputs responsive.
Power & cooling. TDP is APU power, not the whole handheld’s draw. The battery range below includes display and system overhead.
Command Center & AMD quick sheet
- Command Center RSR
- Off The game has FSR 2.1 and XeSS built in. Running both makes the image soft.
- AMD Anti-Lag
- Enabled if available Use the game-specific driver profile; disable it if it causes problems.
- Frame generation
- Off It adds input lag to aim and inputs at this frame rate.
- Update Armoury Crate and AMD drivers through MyASUS.
- Set VRAM to 6GB in the Armoury Crate settings.
- Enable AMD Anti-Lag in the Command Center for better responsiveness.

Heavy impactThese cost the most frames. Drop them first if you need more battery or higher FPS.
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.
What to turn down first

Our pick: Effects
Keep Effects at Medium to prevent massive frame drops during chaotic Purge combat.
The reality check
ROG Ally vs Steam Deck: Warhammer 40,000: Boltgun 2 performance
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
How long is your next session?
Couch mode · 15W APU power
The 900p sweet spot: 1600×900 renders about 30% fewer pixels than 1080p but stays sharp on a 7-inch screen. Add it in Armoury Crate SE’s Command Center for a one-tap switch.
Couch & plugged in
Use 25W with a charger nearby. Keep vents clear and establish a steady frame cap before raising resolution.
On the go
Try the 13W road-trip profile and lower resolution first. If heavy firefights in Warhammer 40,000: Boltgun 2 cannot hold the cap, use the couch profile instead of accepting uneven response.

Your right thumb stays on aim while the paddles handle the rest.
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.
Before you go offline
- Finish downloads and launch the game once while connected.
- Save, switch Steam to Offline Mode, then restart the game with Wi-Fi off.
- Check that your save loads; online modes and launcher sign-ins may still need a connection.
Offline availability depends on the game and its launcher.
Playing tips

The Purge encounters with high enemy counts and heavy Heat Gun usage are the most demanding scenes to test.
Readability
The retro-inspired UI and text elements are perfectly scaled for the 7-inch handheld screen without scaling.
Heat & Fans
The game runs cool on the 15W profile, keeping fan noise low even during extended combat sessions.
Shader Behavior
Expect minor hitches when entering new biomes for the first time while the engine prepares new assets.
