Best Assassin’s Creed Shadows settings for the ROG Ally / Legion Go (Z1 Extreme) (2026)

On a ROG Ally / Legion Go (Z1 Extreme) (paired with a balanced Intel Core i5-8600K-class CPU), Assassin’s Creed Shadows runs at roughly 63 FPS at 1080p with our optimized settings — up from about 24FPS with everything maxed. Here's the configuration and what each setting costs.

The ROG Ally / Legion Go (Z1 Extreme) is a handheld graphics card with 4GB of VRAM, and Assassin’s Creed Shadows is a one of the most punishing games to run on PC. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 63 FPS with FrameCoach's optimized settings, a clear jump from roughly 24 FPS with everything on High.

Across resolutions you can expect around 63 FPS at 1080p and 47 FPS at 1440p, dropping to roughly 27 FPS at 4K. With only 4GB of VRAM, keep textures a notch below max in Assassin’s Creed Shadows at higher resolutions to avoid stutter. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.
