Best Rennsport settings for the AMD RX 6400 (2026)

On a AMD RX 6400 (paired with a balanced Intel Core i5-8600K-class CPU), Rennsport runs at roughly 61 FPS at 1080p with our optimized settings — up from about 32FPS 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 Rennsport is a moderately demanding game. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 61 FPS with FrameCoach's optimized settings, a clear jump from roughly 32 FPS with everything on High.

Across resolutions you can expect around 61 FPS at 1080p and 47 FPS at 1440p, dropping to roughly 27 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

💡 Rennsport: Unreal Engine 5 sim racer - Shadows are the heaviest setting; tune for a locked framerate rather than a high average.
🚀 Biggest free win: enable FSR (Balanced) — about +55% FPS for a small sharpness trade.
Recommended settings
Upscaling — FSRBalanced+55% FPS
Rennsport is an Unreal Engine 5 sim racer with DLSS/FSR support. Sim racing wants high, stable FPS for clean inputs — upscaling is the first lever.
Shadow QualityMedium+6% FPS
Like most UE racers, shadows are the heaviest setting — trackside objects, fences and cars all cast them at speed.
Global Illumination (Lumen)Medium+5% FPS
Lumen lighting on track surfaces and cockpits. High→Medium is a solid win with the smallest visual cost at racing speed.
Reflections QualityMedium+4% FPS
Car paint and mirror reflections. Expensive on a grid full of cars; Medium reads fine at speed.
Crowd / Trackside DetailMedium+3% FPS
Spectators and trackside props — you will never look at them mid-corner.
Effects QualityMedium+2% FPS
Spray, smoke and sparks. Lowering helps most in wet races and pile-ups.
Texture QualityEpic-1% FPS
Livery and track sharpness. Nearly free with 8GB+ VRAM.
Post ProcessingHighbaseline
Motion blur and bloom. Many sim racers turn this down anyway for clarity.
