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.
