Best Arma 3 settings for the AMD RX 6400 (2026)

On a AMD RX 6400 (paired with a balanced Intel Core i5-8600K-class CPU), Arma 3 runs at roughly 67 FPS at 1080p with our optimized settings — up from about 34FPS 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 Arma 3 is a moderately demanding game. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 67 FPS with FrameCoach's optimized settings, a clear jump from roughly 34 FPS with everything on High.

Across resolutions you can expect around 67 FPS at 1080p and 52 FPS at 1440p, dropping to roughly 29 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

💡 Arma 3: Heavily CPU-bound milsim - View Distance and Object View Distance matter most on large missions.
🚀 Biggest free win: enable FSR (Balanced) — about +55% FPS for a small sharpness trade.
Recommended settings
Upscaling — FSRBalanced+55% FPS
Arma 3 renders at a multiple of your resolution (Sampling). Lowering it is the biggest GPU-side lever — but note Arma is mostly CPU-bound.
Overall VisibilityLow+14% FPS
How far the whole world renders — the heaviest setting in Arma and a big CPU cost. Medium transforms FPS on large missions.
Object VisibilityLow+12% FPS
How far buildings, trees and units draw — also heavily CPU-bound. Lower it alongside Overall Visibility for the biggest gains.
Shadow VisibilityMediumbaseline
Shadow detail and range. Medium is a good balance; High is costly over large areas.
Terrain DetailMediumbaseline
Ground mesh and clutter detail. Medium keeps sightlines fair without crushing FPS.
Cloud QualityMediumbaseline
Volumetric cloud detail. Lower it if flying or in heavy weather.
Anti-Aliasing / Post-ProcessLowbaseline
Edge smoothing plus bloom and blur. Many players keep these low for clarity and frames.
Texture QualityHighbaseline
Surface sharpness — cheap on FPS if it fits your VRAM.
