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 176 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 103 FPS. At 4K, all settings exceed 68 FPS.
The GeForce RTX 4090 is 870% above the recommended GPU (GeForce GTX 570) for Hearts of Iron IV. The Xeon E5-2680 v2 is 399% above the recommended CPU (Core i5-750).
At lower resolutions (4k (low/medium/ultra)), the Xeon E5-2680 v2 sets the FPS ceiling. As graphical load increases at (all 1080p settings, all 1440p settings), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 4k high.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p medium, the GeForce RTX 4090 sets the ceiling at about 105 FPS, while the Xeon E5-2680 v2 has headroom up to 318 FPS. In this scenario, the GPU limits the CPU potential by 67% (FPS gap: 213 FPS). Overall distribution: GPU limits 8/12 cells, CPU limits 4/12, balanced 0/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Xeon E5-2680 v2 frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 61% | GPU Limits CPU 67% | GPU Limits CPU 67% | GPU Limits CPU 57% |
| 1440p (2K QHD) | GPU Limits CPU 28% | GPU Limits CPU 24% | GPU Limits CPU 27% | GPU Limits CPU 12% |
| 4K (Ultra HD) | CPU Limits GPU 10% | CPU Limits GPU 14% | CPU Limits GPU 8% | CPU Limits GPU 20% |
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.

The Xeon E5-2680 v2 + GeForce RTX 4090 pairing runs this title with CPU utilization between 57% and 100% and GPU utilization between 16% and 56%. Xeon E5-2680 v2 stays in a controlled operating range, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 22% at 1080p to 48% at 4K, while CPU averages move from 78% to 80%.
The utilization pattern is relatively even. The GeForce RTX 4090 reaches 48% average at its highest-load preset, while the Xeon E5-2680 v2 peaks at 80% average. This suggests a fairly controlled load distribution, but the actual FPS-limiting side should still be read from the limiter analysis above.
At 1080p, averages sit around CPU 78% and GPU 22%. At 1440p, that shifts to CPU 78% and GPU 38%, and at 4K it reaches CPU 80% and GPU 48%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) Low is the most balanced preset based on this dataset. It runs around CPU 80% (59-100%) and GPU 48% (40-56%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Xeon E5-2680 v2 remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Xeon E5-2680 v2 and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

Yes, the Xeon E5-2680 v2 paired with the GeForce RTX 4090 can run Hearts of Iron IV smoothly up to 4k achieving around 68 FPS at Ultra quality. Your GPU is 870% above the recommended specs, and your CPU is 399% above the recommended requirements.
This CPU + GPU combo costs approximately $2111 ($462 CPU + $1649 GPU (Rank #77 Value)). Your GeForce RTX 4090 provides phenomenal top-tier performance but at a premium enthusiast price. Since you are essentially at the ceiling of current hardware capabilities, there are no meaningful performance upgrades available. However, if you wanted a more cost-effective build that still delivers a great experience, you could theoretically step down to a high-end card with a significantly better value rating.
Your GeForce RTX 4090 is already a top-tier graphics card. While it's technically the limiting factor here (which means you are fully utilizing your GPU's visual horsepower exactly as intended), there is no meaningful upgrade path that would drastically improve your Hearts of Iron IV performance right now. GPU fully utilized at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra. CPU-limited at: 4k low, 4k medium, 4k 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 E5-2680 v2 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.
