Known to slow down in the late game due to the exponential number of unit calculations. Single-core CPU speed is the most important factor for performance.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 108 FPS. At 1440p, all settings exceed 100 FPS. At 4K, all settings exceed 90 FPS.
The GeForce RTX 5090 is 889% above the recommended GPU (GeForce GTX 570) for Hearts of Iron IV. The Xeon 6357P is 1094% above the recommended CPU (Core i5-750).
The Xeon 6357P sets the FPS ceiling at all 1080p settings, all 1440p settings, 4k (low/medium), while the GeForce RTX 5090 still has headroom. The FPS ceiling is closely matched at 4k (high/ultra).
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages. Adjacent heavier settings are lightly stabilized to remove prediction jitter that would otherwise create impossible reversals.
At 1080p low, the Xeon 6357P sets the ceiling at about 252 FPS, while the GeForce RTX 5090 could reach 272 FPS. In this scenario, the CPU limits the GPU potential by 7% (FPS gap: 20 FPS). Overall distribution: CPU limits 10/12 cells, GPU limits 0/12, balanced 2/12. Confidence is low because both ceilings are very close in this cell.
The Xeon 6357P and GeForce RTX 5090 stay close in effective frame-generation ceiling across most presets, so neither side consistently suppresses the other by a large margin.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 7% | CPU Limits GPU 7% | CPU Limits GPU 7% | CPU Limits GPU 7% |
| 1440p (2K QHD) | CPU Limits GPU 7% | CPU Limits GPU 7% | CPU Limits GPU 7% | CPU Limits GPU 7% |
| 4K (Ultra HD) | CPU Limits GPU 7% | CPU Limits GPU 6% | Balanced | Balanced |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings and then monotonic-smoothed across heavier presets and resolutions, not generic utilization heuristics.

Yes, the Xeon 6357P paired with the GeForce RTX 5090 can run Hearts of Iron IV smoothly up to 4k achieving around 90 FPS at Ultra quality. Your GPU is 889% above the recommended specs, and your CPU is 1094% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For Hearts of Iron IV, upgrading the CPU would have the biggest impact on performance. The Xeon 6357P is currently the limiting factor — the GeForce RTX 5090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium.
Hearts of Iron IV does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
Hearts of Iron IV requires at minimum a Core 2 Quad Q9400 (CPU) and GeForce GTX 470 (GPU) with 4 GB RAM and 2 GB storage. For the recommended experience, you need a Core i5-750 and GeForce GTX 570 with 4 GB RAM. Your Xeon 6357P and GeForce RTX 5090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Hearts of Iron IV FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
