Rock Paper Shotgun "The Resynced version runs significantly better on the Steam Deck than the original release, with a 20% improvement in frame rate consistency."

Performance scales with TDP: at 12W the game can reach 50–60 FPS but reduces battery life to under 2 hours. At 7W the frame rate drops to 25–30 FPS, extending battery life to nearly 3 hours. The optimal balance for most players is 9W with medium settings.

What Are the Optimal Settings for Assassin's Creed Black Flag Resynced on Steam Deck?

The optimal settings for smooth performance on the Steam Deck are: resolution 1280x800, graphics quality preset Medium, anti-aliasing FXAA, shadows Low, ambient occlusion Off, and post-processing Low. These settings yield 30–45 FPS at 9W TDP. Using the Medium preset with FXAA and Low shadows provides the best balance of visual quality and performance on the Steam Deck.

Rock Paper Shotgun recommends disabling the in-game frame rate cap and instead using the Steam Deck's built-in 30 FPS limiter to reduce input latency. Additionally, setting the GPU clock to 1000 MHz in the Quick Access menu can stabilize frame times. The Resynced version includes a dedicated "Steam Deck" preset that automatically applies these optimizations.

How Does the Resynced Version Compare to the Original Release?

The Resynced version of Assassin's Creed IV Black Flag includes specific optimizations for the Steam Deck and Steam Machine, such as improved shader compilation, reduced CPU overhead, and a native 1280x800 resolution mode. In Rock Paper Shotgun's benchmarks, the Resynced version runs 15–20% faster than the original release on the same hardware. The Resynced edition reduces stutter by 30% compared to the original game on the Steam Deck.

For desktop PCs, the Resynced version also adds support for higher frame rates and ultrawide monitors, but the handheld optimizations are the primary focus. The original release required manual tweaks to achieve playable performance on the Steam Deck, whereas the Resynced version works out of the box.
