Best War Thunder settings for the AMD RX 6400 (2026)

On a AMD RX 6400 (paired with a balanced Intel Core i5-8600K-class CPU), War Thunder runs at roughly 64 FPS at 1080p with our optimized settings — up from about 41FPS with everything maxed. Here's the configuration and what each setting costs.

The AMD RX 6400 is a entry-level 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 64 FPS with FrameCoach's optimized settings, a clear jump from roughly 41 FPS with everything on High.

Across resolutions you can expect around 64 FPS at 1080p and 58 FPS at 1440p, dropping to roughly 33 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

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