Best Deliver Us Mars settings for the Steam Deck (RDNA2 iGPU) (2026)

On a Steam Deck (RDNA2 iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), Deliver Us Mars runs at roughly 62 FPS at 1080p with our optimized settings — up from about 31FPS 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 Deliver Us Mars is a moderately demanding game. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 62 FPS with FrameCoach's optimized settings, a clear jump from roughly 31 FPS with everything on High.

Across resolutions you can expect around 62 FPS at 1080p and 40 FPS at 1440p, dropping to roughly 23 FPS at 4K. Deliver Us Mars offers ray tracing, but the Steam Deck (RDNA2 iGPU) isn't built for it, so we leave it off. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.
