Best Assetto Corsa settings for the NVIDIA RTX 4090 (2026)

On a NVIDIA RTX 4090 (paired with a balanced Intel Core i9-14900K-class CPU), Assetto Corsa runs at roughly 159 FPS at 4K with our optimized settings — up from about 159FPS with everything maxed. Here's the configuration and what each setting costs.

The NVIDIA RTX 4090 is a flagship 4K-class graphics card with 24GB of VRAM, and Assetto Corsa is a relatively light game to run. Paired with the Intel Core i9-14900K, it flies at 4K — about 159 FPSwith 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 263 FPS at 1080p and 263 FPS at 1440p, dropping to roughly 159 FPS at 4K. Its 24GB of VRAM is plenty for Assetto Corsa, 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.

💡 Assetto Corsa: Reflections and shadows are the heavy hitters; resolution scale matters most for the high, steady FPS sim racing needs.
Recommended settings
Upscaling — DLSSOff
Render resolution scaling is the biggest GPU-side FPS lever — important for hitting the high, steady frame rates sim racing (and VR) needs.
Reflection Resolution / FrequencyHighbaseline
The cubemap reflections on your car. One of the heaviest settings — lowering the resolution and update frequency is a big, barely-noticeable gain while driving.
Shadow ResolutionHighbaseline
Shadow detail trackside. High is a strong step down from Ultra with little visible loss at speed.
World DetailHighbaseline
Trackside objects and crowds. Costly, and you blow past most of it at racing speed.
Mirror ResolutionHighbaseline
How sharp your mirrors render. Medium is fine for race awareness and saves frames.
Smoke GenerationMediumbaseline
Tyre smoke detail. Drops most during heavy braking and drifts — lower it if those moments stutter.
Anti-AliasingMediumbaseline
Smooths jagged edges — important for distant track edges. Lower a notch if you need frames.
Texture QualityHighbaseline
Surface detail — nearly free if it fits your VRAM. Fine at High on most cards.
Anisotropic Filtering16xbaseline
Keeps the track surface sharp into the distance. Effectively free — leave it at 16x.
