Best War Thunder settings for the Steam Deck (RDNA2 iGPU) (2026)

On a Steam Deck (RDNA2 iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), War Thunder runs at roughly 62 FPS at 1080p with our optimized settings — up from about 39FPS 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 War Thunder 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 39 FPS with everything on High.

Across resolutions you can expect around 62 FPS at 1080p and 55 FPS at 1440p, dropping to roughly 31 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

Resolution	All-High FPS	Optimized FPS
1080p	39	62
1440p	23	55
4K	13	31

💡 War Thunder: Dagor engine - smoke effects are the biggest FPS drain in battle, and big matches can be CPU-bound.

🚀 Biggest free win: enable FSR (Balanced) — about +55% FPS for a small sharpness trade.

Recommended settings

Upscaling — FSRBalanced+55% FPS

War Thunder supports DLSS and FSR. The biggest FPS gain — turn it on first, especially at 1440p and up.

Cloud QualityMedium+3% FPS

Volumetric cloud detail — matters most in air battles. A cheap, near-invisible saving on the ground.

Shadow QualityHighbaseline

Shadow resolution and range over large maps. High is a strong, good-looking step down from Ultra.

Grass RangeMediumbaseline

Density and render distance of grass. Costly, and lower settings also stop foliage hiding tanks at range.

Particle DensityHighbaseline

Explosion embers, sparks and smoke — and in War Thunder, smoke tanks FPS in busy fights. Lowering it keeps you steady when it counts.

Water QualityHighbaseline

Water detail and the quality of reflections on its surface. Safe to lower with little visible loss in combat.

SSAOHighbaseline

Screen-space ambient occlusion — soft contact shadows (also enables small-object shadows). Low is a cheap, clean win.

Texture QualityHighbaseline

Surface detail — nearly free if it fits your VRAM. Fine at High on most cards.

Anisotropic Filtering16xbaseline

Keeps ground textures sharp at distance. Effectively free — leave it at 16x.
