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 122 FPS. At 1440p, all settings exceed 111 FPS. At 4K, all settings exceed 100 FPS.
The GeForce RTX 5090 is 889% above the recommended GPU (GeForce GTX 570) for Hearts of Iron IV. The Core Ultra 5 245K is 1605% above the recommended CPU (Core i5-750).
The Core Ultra 5 245K sets the FPS ceiling at 1080p (low/medium), 1440p (low/medium), while the GeForce RTX 5090 still has headroom. The FPS ceiling is closely matched at 1080p (high/ultra), 1440p (high/ultra), all 4k settings.
Approximated average price on current market:
Combo price: $2900. At 1080p Ultra, this combo delivers 122 FPS, equivalent to 0.04 FPS per dollar.

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 Core Ultra 5 245K sets the ceiling at about 238 FPS, while the GeForce RTX 5090 could reach 259 FPS. In this scenario, the CPU limits the GPU potential by 8% (FPS gap: 21 FPS). Overall distribution: CPU limits 4/12 cells, GPU limits 0/12, balanced 8/12. Confidence is low because both ceilings are very close in this cell.
The Core Ultra 5 245K 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 8% | CPU Limits GPU 6% | Balanced | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 8% | CPU Limits GPU 6% | Balanced | Balanced |
| 4K (Ultra HD) | Balanced | Balanced | 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 Core Ultra 5 245K paired with the GeForce RTX 5090 can run Hearts of Iron IV smoothly up to 4k achieving around 100 FPS at Ultra quality. Your GPU is 889% above the recommended specs, and your CPU is 1605% above the recommended requirements.
This CPU + GPU combo costs approximately $2900 ($200 CPU + $2700 GPU). Your Core Ultra 5 245K 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 processor with a significantly better value rating. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #4 for value).
Your Core Ultra 5 245K is already an incredibly powerful processor. While it's technically the first component to hit its limit (which is completely normal in state-of-the-art builds), there is no meaningful upgrade path that would drastically improve your Hearts of Iron IV performance right now. CPU fully utilized at: 1080p low, 1080p medium, 1440p low, 1440p 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 Ultra 5 245K 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.
