Best Split Fiction settings for the NVIDIA RTX 4090 (2026)

On a NVIDIA RTX 4090 (paired with a balanced Intel Core i9-14900K-class CPU), Split Fiction runs at roughly 91 FPS at 4K with our optimized settings — up from about 92FPS 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 Split Fiction is a moderately demanding game. Paired with the Intel Core i9-14900K, it runs great at 4K — about 91 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 263 FPS at 1080p and 160 FPS at 1440p, dropping to roughly 91 FPS at 4K. Its 24GB of VRAM is plenty for Split Fiction, 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.

Recommended settings
Upscaling — DLSSOff
Split Fiction (Unreal Engine 5) supports DLSS, FSR and XeSS plus Frame Generation. A free FPS boost on a well-optimised game.
Texture QualityEpic-1% FPS
Surface sharpness - cheap if it fits your VRAM.
Shadow QualityHighbaseline
Shadow resolution and range. High is the value pick.
Shader QualityHighbaseline
Material shading detail - drastically impacts performance in this game. High is a clean trade over Epic.
Effects QualityHighbaseline
Particle effects - sand, smoke, debris and explosions across the wild set-pieces. Lowering smooths the busiest moments.
Detail LevelHighbaseline
Level of detail (LOD) - how far objects render at full quality. Mild pop-in when lowered.
Post-Processing QualityHighbaseline
Bloom, motion blur and depth of field. Cheap; set to taste.
Anti-AliasingHighbaseline
Edge smoothing (Temporal AA / FSR 3). Medium/High keeps the image clean cheaply.
Anisotropic Filtering16xbaseline
Keeps surfaces sharp at distance. Effectively free - leave it at 16x.
