Best Phantom Blade Zero settings for the Steam Deck (RDNA2 iGPU) (2026)

On a Steam Deck (RDNA2 iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), Phantom Blade Zero runs at roughly 59 FPS at 1080p with our optimized settings — up from about 23FPS with everything maxed. Here's the configuration and what each setting costs.

The Steam Deck (RDNA2 iGPU) is a handheld graphics card with 4GB of VRAM, and Phantom Blade Zero is a demanding, graphically heavy game. Paired with the Intel Core i5-8600K, it is playable at 1080p — about 59 FPS with FrameCoach's optimized settings, a clear jump from roughly 23 FPS with everything on High.

Across resolutions you can expect around 59 FPS at 1080p and 36 FPS at 1440p, dropping to roughly 20 FPS at 4K. Phantom Blade Zero offers ray tracing, but the Steam Deck (RDNA2 iGPU) isn't built for it, so we leave it off. With only 4GB of VRAM, keep textures a notch below max in Phantom Blade Zero 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.
