Best Diablo IV settings for the NVIDIA GTX 1630 (4GB) (2026)
On a NVIDIA GTX 1630 (4GB) (paired with a balanced Intel Core i5-8600K-class CPU), Diablo IV runs at roughly 60 FPS at 1080p with our optimized settings — up from about 30FPS with everything maxed. Here's the configuration and what each setting costs.
The NVIDIA GTX 1630 (4GB) is a entry-level 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 60 FPSwith FrameCoach's optimized settings, a clear jump from roughly 30 FPS with everything on High.
Across resolutions you can expect around 60 FPS at 1080p and 46 FPS at 1440p, dropping to roughly 26 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 — FSRBalanced+55% FPS
Supports DLSS (RTX), FSR and XeSS. A big GPU-side boost, though Diablo IV is well optimized to begin with.
Shadow QualityMedium+5% FPS
Shadow resolution and filtering. High is a clean trade over Ultra.
Screen Space Ambient OcclusionMedium+3% FPS
Soft contact shadows. Cheap; Medium is plenty for the top-down view.
Fog QualityMedium+3% FPS
Volumetric fog in dungeons and the open world. A low-risk saving.
Reflection QualityMedium+3% FPS
Reflections on wet floors and water. Often subtle from the isometric camera.
Clutter / Particle QualityMedium+2% FPS
On-screen effects and debris. Lowering smooths busy fights with lots of mobs.
Anti-AliasingMedium+2% FPS
Edge smoothing. Medium keeps the image clean cheaply.
Geometric ComplexityMedium+2% FPS
Detail on environment and dungeon geometry. High over the top-down camera is plenty.
Shadow Filtering QualityMedium+2% FPS
How softly shadow edges blur. Medium is a cheap, clean middle ground.
Water Simulation QualityMedium+2% FPS
Ripples and flow on water surfaces. A low-risk saving from the isometric view.
DistortionOff+2% FPS
Heat-haze and magic-warp effects. Nearly free; set to taste.
Texture QualityUltra-1% FPS
Diablo IV is VRAM-hungry — Ultra textures want 10GB+. On 8GB cards, High avoids stutter.
Anisotropic Filtering16xbaseline
Keeps the ground sharp at angles — essentially free, use 16x.
