Tested settings.Zero guesswork.

Tested in Batman: Arkham Knight at 1920x1080 using a 35W performance profile. The result is best treated as a Balanced 50 FPS preset with strong visual quality. Gameplay stays comfortably above a 40 FPS target most of the time, although heavier scenes can still cause short frametime spikes.

Balanced 40 FPS preset for Assassin’s Creed Origins on the ROG Xbox Ally X. Tested at 1920x1080 with a 35W performance profile. Across three CapFrameX runs, the game averaged around 42 FPS with a 1% Low of approximately 32 FPS. This preset is aimed at smooth and stable open-world gameplay rather than high refresh-rate performance. Frame pacing is generally solid for a 40 FPS target, although heavier city areas, fast traversal or dense scenes may still cause occasional short drops.

Tested at 1920x1080 using a 35W performance profile with Windowed Full-Screen mode, V-Sync Off, Max FPS set to 240 and no main screen frame rate limit. The preset uses AMD FidelityFX Super Resolution set to Performance mode with FSR Frame Generation enabled. Variable Rate Rendering was disabled. Custom performance-focused settings were used: Basic view distance, shadows, effects, vegetation, shaders, lighting and world detail; Balanced internal resolution and texture quality; Quality post-processing; and Performance scope quality. Across three CapFrameX runs, performance averaged around 80 FPS with an average 1% low of approximately 31 FPS. The game feels fast overall, but the low 1% and 0.1% values show occasional frametime spikes or heavier scene transitions.

Devil May Cry 5 was tested at native 1920×1080 resolution on the ROG Xbox Ally X using a 35 W docked power profile. The game was configured with a custom High/Ultra visual quality preset. Ambient occlusion, lighting and vegetation were set to Ultra, while anti-aliasing, textures, shadows, mesh quality and texture filtering were set to High. Tessellation, depth of field, motion blur, HDR output and high mip preloading were enabled. Dynamic resolution and V-Sync were disabled. During the stable gameplay segment, the benchmark averaged 46.6 FPS with a 1% low of 34.8 FPS and a 0.1% low of 33.9 FPS. GPU usage stayed very high at around 96%, indicating a mostly GPU-limited scenario.

Recommended balanced preset for Cyberpunk 2077 on ROG Ally Z1 Extreme. Delivers over 50 FPS while maintaining sharper visuals than 720p. Excellent compromise between performance and image quality.

This preset is tuned for crisp image quality while maintaining an average of 83 FPS, with a maximum of 100 FPS and a minimum of 70 FPS. The available performance headroom also allows you to increase selected graphics settings for even better visual quality based on your personal preferences.
