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 158 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 121 FPS. At 4K, all settings exceed 82 FPS.
The GeForce RTX 4090 is 870% above the recommended GPU (GeForce GTX 570) for Hearts of Iron IV. The Core i9-10900KF is 773% above the recommended CPU (Core i5-750).
At lower resolutions (4k (low/medium)), the Core i9-10900KF determines the performance ceiling. As graphical load increases at (all 1080p settings, all 1440p settings), the GeForce RTX 4090 takes over as the primary performance factor. The system is well balanced at 4k (high/ultra).
Approximated average price on current market:
Combo price: $1985. At 1080p Ultra, this combo delivers 158 FPS, equivalent to 0.08 FPS per dollar.

At 1080p high, the GeForce RTX 4090 sets the ceiling at about 76 FPS, while the Core i9-10900KF has headroom up to 175 FPS. In this scenario, the GPU limits the CPU potential by 57% (FPS gap: 99 FPS). Overall distribution: GPU limits 8/12 cells, CPU limits 2/12, balanced 2/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Core i9-10900KF frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 51% | GPU Limits CPU 54% | GPU Limits CPU 57% | GPU Limits CPU 53% |
| 1440p (2K QHD) | GPU Limits CPU 25% | GPU Limits CPU 25% | GPU Limits CPU 31% | GPU Limits CPU 26% |
| 4K (Ultra HD) | CPU Limits GPU 8% | 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.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

Yes, the Core i9-10900KF paired with the GeForce RTX 4090 can run Hearts of Iron IV smoothly up to 4k achieving around 82 FPS at Ultra quality. Your GPU is 870% above the recommended specs, and your CPU is 773% above the recommended requirements.
This CPU + GPU combo costs approximately $1985 ($336 CPU (Rank #290 Value) + $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.
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 Core i9-10900KF 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.
