On a ROG Ally X (Z1 Extreme) (paired with a balanced Intel Core i5-8600K-class CPU), Diablo IV runs at roughly 80 FPS at 1080p with our optimized settings — up from about 60FPS with everything maxed. Here's the configuration and what each setting costs.

The ROG Ally X (Z1 Extreme) is a handheld graphics card with 4GB of VRAM, and Diablo IV is a moderately demanding game. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 80 FPS with FrameCoach's optimized settings, a clear jump from roughly 60 FPS with everything on High.

Across resolutions you can expect around 80 FPS at 1080p and 62 FPS at 1440p, dropping to roughly 52 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

Recommended settings
Upscaling — FSRQuality+35% FPS
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.
