Diablo IV FPS Calculator

Diablo IV brings players back to a grim Sanctuary, packed with satisfying skill effects, countless enemies on screen, and gorgeous isometric environments. Running Diablo IV requires a CPU score of at least 62 and a GPU score of at least 58. The game scales well across a wide range of hardware — minimum-spec machines can hit a playable frame rate at reduced settings, while recommended hardware (CPU 76, GPU 74) targets 100 FPS at 1080p. Use the FPS calculator to test your specific CPU and GPU combination at 1080p, 1440p, or 4K.

The minimum PC requirements for Diablo IV are: CPU — Intel Core i5-2500K or AMD FX-8350; GPU — NVIDIA GeForce GTX 660 or AMD Radeon R9 280; RAM — 8 GB RAM; Storage — 90 GB available space; OS — 64-bit Windows 10 version 1909 or newer. Hardware at this tier can run the game at low graphics settings, typically achieving around 30 FPS at 1080p. Performance may feel inconsistent during CPU-heavy or GPU-heavy sequences. Using an SSD instead of a hard drive and keeping background applications closed can meaningfully reduce stuttering even without a GPU upgrade.

The recommended PC requirements for Diablo IV are: CPU — Intel Core i5-4670K or AMD Ryzen 3 1300X; GPU — NVIDIA GeForce GTX 970 or AMD Radeon RX 470; RAM — 16 GB RAM; Storage — 90 GB available space. This hardware tier is tuned for around 100 FPS at 1080p on high graphics settings. Moving to 1440p at the same quality requires a GPU score meaningfully above 74. Use the FPS calculator to identify which specific CPU and GPU combinations hit your target frame rate at each resolution.

On hardware meeting Diablo IV's recommended specifications, expect around 100 FPS at 1080p on high settings. Minimum-spec hardware typically lands in the 30–45 FPS range on low-to-medium presets at the same resolution. Moving to 1440p reduces the frame rate by roughly 25–35%, and 4K roughly halves 1080p performance. Frame time consistency matters as much as the average: capping near your monitor's refresh rate can smooth out dips. Enter your components in our FPS calculator for a tailored projection including per-resolution estimates.

At 1080p, Diablo IV needs a GPU with a minimum score of 58 — the equivalent of NVIDIA GeForce GTX 660 or AMD Radeon R9 280. For smooth, consistent performance at 1080p on high settings, target the recommended score of 74 (NVIDIA GeForce GTX 970 or AMD Radeon RX 470). Scaling to 1440p typically calls for a GPU scoring around 96, and 4K demands significantly more headroom. GPU performance score is derived from multi-game benchmark data and allows direct comparison across NVIDIA, AMD, and Intel Arc cards. Use the FPS calculator to match any GPU in our database against Diablo IV's requirements.

Diablo IV is primarily GPU-bound for raw frame rate output, but a CPU below the minimum score of 62 can create a bottleneck in complex scenes. The recommended CPU score of 76 (Intel Core i5-4670K or AMD Ryzen 3 1300X) is calibrated to keep the processor from limiting GPU utilisation. If your GPU significantly exceeds the recommended score while your CPU sits near the minimum, you may notice inconsistent frame times during busy sequences. Our FPS calculator models CPU-GPU pairing and surfaces bottleneck warnings when components are significantly mismatched.
