Best Rennsport settings for the RTX 4090 Laptop (2026)

On a RTX 4090 Laptop (paired with a balanced Intel Core i9-12900F-class CPU), Rennsport runs at roughly 110 FPS at 1440p with our optimized settings — up from about 111FPS with everything maxed. Here's the configuration and what each setting costs.

The RTX 4090 Laptop is a high-end graphics card with 16GB of VRAM, and Rennsport is a moderately demanding game. Paired with the Intel Core i9-12900F, it runs great at 1440p — about 110 FPS with FrameCoach's optimized settings. That already clears a smooth frame rate on High, so our tuning keeps the visuals as high as possible instead of chasing extra frames.

Across resolutions you can expect around 184 FPS at 1080p and 110 FPS at 1440p, dropping to roughly 62 FPS at 4K. Its 16GB of VRAM is plenty for Rennsport, so textures can stay maxed. The biggest free win is DLSS 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.
Recommended settings
Upscaling — DLSSOff
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.
Texture QualityEpic-1% FPS
Livery and track sharpness. Nearly free with 8GB+ VRAM.
Shadow QualityHighbaseline
Like most UE racers, shadows are the heaviest setting — trackside objects, fences and cars all cast them at speed.
Global Illumination (Lumen)Highbaseline
Lumen lighting on track surfaces and cockpits. High→Medium is a solid win with the smallest visual cost at racing speed.
Reflections QualityHighbaseline
Car paint and mirror reflections. Expensive on a grid full of cars; Medium reads fine at speed.
Crowd / Trackside DetailHighbaseline
Spectators and trackside props — you will never look at them mid-corner.
Effects QualityHighbaseline
Spray, smoke and sparks. Lowering helps most in wet races and pile-ups.
Post ProcessingHighbaseline
Motion blur and bloom. Many sim racers turn this down anyway for clarity.
