Best Marathon settings for the AMD RX 6400 (2026)

On a AMD RX 6400 (paired with a balanced Intel Core i5-8600K-class CPU), Marathon runs at roughly 60 FPS at 1080p with our optimized settings — up from about 26FPS 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 Marathon is a demanding, graphically heavy game. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 60 FPS with FrameCoach's optimized settings, a clear jump from roughly 26 FPS with everything on High.

Across resolutions you can expect around 60 FPS at 1080p and 37 FPS at 1440p, dropping to roughly 21 FPS at 4K. With only 4GB of VRAM, keep textures a notch below max in Marathon at higher resolutions to avoid stutter. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

💡 Marathon: Bungie extraction shooter - busy zones are partly CPU-bound; upscaling helps the GPU side.
🚀 Biggest free win: enable FSR (Balanced) — about +55% FPS for a small sharpness trade.
Recommended settings
Upscaling — FSRBalanced+55% FPS
Supports DLSS and FSR. The biggest single FPS gain — turn it on first, especially at 1440p and up.
Shadow QualityLow+12% FPS
Shadow resolution and range. High is a big saving over Epic with little visible difference in a fight.
View DistanceLow+11% FPS
How far the map and players render — key for spotting threats in an extraction shooter, and partly CPU-bound.
Effects QualityLow+8% FPS
Gunfire and ability effects. Drops most in firefights — lower it to stay steady.
Foliage / DetailLow+7% FPS
Environment density. Cheap to lower, and less cover hiding enemies.
Post ProcessingLow+5% FPS
Bloom and lens effects. Low gives a cleaner, clearer image.
Texture QualityEpic-1% FPS
Surface detail — nearly free if it fits your VRAM. On 8GB cards keep it at High.
Anisotropic Filtering16xbaseline
Keeps ground textures sharp at distance. Effectively free — leave it at 16x.
