On a Steam Deck (RDNA2 iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), Honkai: Star Rail runs at roughly 60 FPS at 1080p with our optimized settings — up from about 60FPS 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 Honkai: Star Rail is a relatively light game to run. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 60 FPSwith FrameCoach's optimized settings. That already clears a smooth frame rate on High, so our tuning keeps the visuals as high as possible instead of chasing extra frames.
Across resolutions you can expect around 60 FPS at 1080p and 60 FPS at 1440p, dropping to roughly 45 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.
