Best Rainbow Six Siege settings for the Steam Deck (RDNA2 iGPU) (2026)

On a Steam Deck (RDNA2 iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), Rainbow Six Siege runs at roughly 70 FPS at 1080p with our optimized settings — up from about 71FPS 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 Rainbow Six Siege is a lightweight, high-frame-rate esports title. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 70 FPS with 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 70 FPS at 1080p and 65 FPS at 1440p, dropping to roughly 58 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

Recommended settings
Upscaling — FSROff
Siege supports DLSS and FSR. The game is extremely well optimized, so this mostly helps at 1440p/4K or on weaker GPUs.
Texture QualityUltra-1% FPS
Surface sharpness — cheap if it fits your VRAM.
Shadow QualityHighbaseline
The main GPU cost. Note: shadows carry information in Siege, so many players keep at least Medium.
Reflection QualityHighbaseline
Surface reflections. Cheap to lower with little gameplay impact.
Ambient OcclusionHBAO+baseline
Contact shadows. SSBC is a cheaper alternative to HBAO+.
Shading QualityHighbaseline
Surface shading detail. Modest cost; safe to lower for frames.
Level of DetailHighbaseline
World geometry detail and draw distance.
Anti-AliasingTAAbaseline
Edge smoothing. TAA is cheap and clean; FXAA is even lighter.
Texture Filtering16xbaseline
Keeps long hallways sharp — effectively free, use 16x.
Lens EffectsOnbaseline
Lens flares and bloom. Nearly free; pure preference.
Zoom-in Depth of FieldOnbaseline
Background blur while aiming down sights. Cheap; many disable it for clarity.
Multisample Anti-Aliasing2xbaseline
Hardware edge smoothing - heavy at higher steps. Off or 2x for high FPS.
