Halo Campaign Evolved struggles to maintain a stable 30 FPS on the Steam Deck, particularly in open-world environments and high-CPU usage areas. Despite its Steam Deck Verified status, the game frequently drops to 24–27 FPS during large-scale battles and vehicle-heavy missions. Performance is most stable in enclosed, indoor environments where the frame rate can exceed 30 FPS, but these gains are lost once players transition to the game's signature expansive outdoor levels. Testing indicates that the optimal configuration for the handheld is the "Very Low" quality preset combined with Temporal Super Resolution (TSR) upscaling set to a 70% resolution scale. While AMD FidelityFX Super Resolution (FSR) is available, it results in significant visual degradation, including shimmering and pixelation, without offering a performance advantage over TSR. Manual GPU clock adjustments were required during testing to address issues where the system failed to fully utilize available resources. The reviewer concludes that the game does not meet Valve's documented criteria for the Verified badge, as it cannot sustain 30 FPS at 800p in demanding scenarios, especially when enemy counts increase on higher difficulties like Legendary mode.
Halo Campaign Evolved frequently drops below 30 FPS in open-world environments and large-scale battles on the Steam Deck. The game's performance is most stable in enclosed, indoor environments where it can consistently exceed 30 FPS.
Recommended settings for the Steam Deck include the Very Low quality preset with TSR upscaling set to a 70% resolution scale. AMD FSR upscaling produces poor visual quality with significant pixelation and shimmering compared to TSR at similar performance levels.
Frame rates can drop as low as 24 FPS during intensive combat sequences, particularly in missions involving vehicles. Higher difficulty settings like Legendary mode slightly decrease performance due to increased enemy counts on screen.
The reviewer disputes the game's Steam Deck Verified status because it fails to maintain a consistent 30 FPS at 800p.
