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.

Performance Report
At 1080p, all quality settings exceed 95 FPS. At 1440p, all settings exceed 77 FPS. At 4K, all settings exceed 63 FPS.
The GeForce RTX 4090 is 870% above the recommended GPU (GeForce GTX 570) for Hearts of Iron IV. The Xeon E5-2683 v4 is 586% above the recommended CPU (Core i5-750).
At lower resolutions (1440p ultra, all 4k settings), the Xeon E5-2683 v4 sets the FPS ceiling. As graphical load increases at (all 1080p settings), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1440p (low/medium/high).
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the GeForce RTX 4090 sets the ceiling at about 136 FPS, while the Xeon E5-2683 v4 has headroom up to 211 FPS. In this scenario, the GPU limits the CPU potential by 36% (FPS gap: 75 FPS). Overall distribution: GPU limits 4/12 cells, CPU limits 5/12, balanced 3/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Xeon E5-2683 v4 frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 36% | GPU Limits CPU 35% | GPU Limits CPU 36% | GPU Limits CPU 18% |
| 1440p (2K QHD) | Balanced | Balanced | Balanced | CPU Limits GPU 14% |
| 4K (Ultra HD) | CPU Limits GPU 17% | CPU Limits GPU 19% | CPU Limits GPU 12% | CPU Limits GPU 24% |
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, not generic utilization heuristics.

Yes, the Xeon E5-2683 v4 paired with the GeForce RTX 4090 can run Hearts of Iron IV smoothly up to 4k achieving around 63 FPS at Ultra quality. Your GPU is 870% above the recommended specs, and your CPU is 586% 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 E5-2683 v4 is currently the limiting factor — the GeForce RTX 4090 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: 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra. GPU fully utilized at: 1080p low, 1080p medium, 1080p high, 1080p ultra.
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 E5-2683 v4 and GeForce RTX 4090 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.
