Best Diablo IV settings for the NVIDIA RTX 3090 (2026)

On a NVIDIA RTX 3090 (paired with a balanced Intel Core i9-12900F-class CPU), Diablo IV runs at roughly 145 FPS at 1440p with our optimized settings — up from about 146FPS with everything maxed. Here's the configuration and what each setting costs.

The NVIDIA RTX 3090 is a high-end graphics card with 24GB of VRAM, and Diablo IV is a moderately demanding game. Paired with the Intel Core i9-12900F, it flies at 1440p — about 145 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 227 FPS at 1080p and 145 FPS at 1440p, dropping to roughly 82 FPS at 4K. Its 24GB of VRAM is plenty for Diablo IV, 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
Supports DLSS (RTX), FSR and XeSS. A big GPU-side boost, though Diablo IV is well optimized to begin with.
Texture QualityUltra-1% FPS
Diablo IV is VRAM-hungry — Ultra textures want 10GB+. On 8GB cards, High avoids stutter.
Shadow QualityHighbaseline
Shadow resolution and filtering. High is a clean trade over Ultra.
Screen Space Ambient OcclusionHighbaseline
Soft contact shadows. Cheap; Medium is plenty for the top-down view.
Fog QualityHighbaseline
Volumetric fog in dungeons and the open world. A low-risk saving.
Reflection QualityHighbaseline
Reflections on wet floors and water. Often subtle from the isometric camera.
Clutter / Particle QualityHighbaseline
On-screen effects and debris. Lowering smooths busy fights with lots of mobs.
Anti-AliasingHighbaseline
Edge smoothing. Medium keeps the image clean cheaply.
Anisotropic Filtering16xbaseline
Keeps the ground sharp at angles — essentially free, use 16x.
Shadow Filtering QualityHighbaseline
How softly shadow edges blur. Medium is a cheap, clean middle ground.
Geometric ComplexityHighbaseline
Detail on environment and dungeon geometry. High over the top-down camera is plenty.
Water Simulation QualityHighbaseline
Ripples and flow on water surfaces. A low-risk saving from the isometric view.
DistortionOnbaseline
Heat-haze and magic-warp effects. Nearly free; set to taste.
