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 65 FPS. At 1440p, frame rates range from 57 to 122 FPS. At 4K, frame rates range from 48 to 108 FPS.
The GeForce RTX 4090 is 870% above the recommended GPU (GeForce GTX 570) for Hearts of Iron IV. The Ryzen 3 PRO 8300GE is 644% above the recommended CPU (Core i5-750).
At lower resolutions (1080p ultra, all 1440p settings, all 4k settings), the Ryzen 3 PRO 8300GE sets the FPS ceiling. As graphical load increases at (1080p (low/medium/high)), the GeForce RTX 4090 becomes the FPS-limiting side.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k low, the Ryzen 3 PRO 8300GE sets the ceiling at about 107 FPS, while the GeForce RTX 4090 could reach 178 FPS. In this scenario, the CPU limits the GPU potential by 40% (FPS gap: 71 FPS). Overall distribution: CPU limits 9/12 cells, GPU limits 3/12, balanced 0/12.
Your Ryzen 3 PRO 8300GE is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 10% | GPU Limits CPU 10% | GPU Limits CPU 14% | CPU Limits GPU 12% |
| 1440p (2K QHD) | CPU Limits GPU 25% | CPU Limits GPU 29% | CPU Limits GPU 23% | CPU Limits GPU 36% |
| 4K (Ultra HD) | CPU Limits GPU 40% | CPU Limits GPU 40% | CPU Limits GPU 33% | CPU Limits GPU 40% |
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 Ryzen 3 PRO 8300GE + GeForce RTX 4090 pairing runs this title with CPU utilization between 48% and 100% and GPU utilization between 11% and 56%. Ryzen 3 PRO 8300GE stays in a controlled operating range, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 19% at 1080p to 44% at 4K, while CPU averages move from 72% to 74%.
The utilization pattern is relatively even. The GeForce RTX 4090 reaches 44% average at its highest-load preset, while the Ryzen 3 PRO 8300GE peaks at 76% 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 72% and GPU 19%. At 1440p, that shifts to CPU 76% and GPU 35%, and at 4K it reaches CPU 74% and GPU 44%. 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 74% (48-100%) and GPU 44% (33-56%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen 3 PRO 8300GE remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 3 PRO 8300GE 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 Ryzen 3 PRO 8300GE paired with the GeForce RTX 4090 can run Hearts of Iron IV smoothly up to 1080p achieving around 65 FPS at Ultra quality. Your GPU is 870% above the recommended specs, and your CPU is 644% 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 Ryzen 3 PRO 8300GE 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: 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra. GPU fully utilized at: 1080p low, 1080p medium, 1080p high.
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 Ryzen 3 PRO 8300GE 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.
