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

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k medium, the Radeon RX 6400 sets the ceiling at about 33 FPS, while the Ryzen 7 7800X3D has headroom up to 236 FPS. In this scenario, the GPU limits the CPU potential by 86% (FPS gap: 203 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your Radeon RX 6400 is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 7800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 81% | GPU Limits CPU 83% | GPU Limits CPU 79% | GPU Limits CPU 76% |
| 1440p (2K QHD) | GPU Limits CPU 83% | GPU Limits CPU 84% | GPU Limits CPU 81% | GPU Limits CPU 80% |
| 4K (Ultra HD) | GPU Limits CPU 84% | GPU Limits CPU 86% | GPU Limits CPU 83% | GPU Limits CPU 81% |
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 7 7800X3D and Radeon RX 6400 will struggle to run Hearts of Iron IV at smooth framerates. At 1080p Ultra, you can expect around 49 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $523 ($384 CPU (Rank #212 Value) + $139 GPU (Rank #36 Value)). Your build is already very cost-efficient, but if you want even more FPS, the next good option is upgrading the GPU. For example, upgrading to the GeForce RTX 5060 for around $299 (Rank #2 for value) could deliver noticeably better performance.
For Hearts of Iron IV, upgrading the GPU would give you the most noticeable improvement. The Radeon RX 6400 is the limiting factor here, while the Ryzen 7 7800X3D still has spare capacity. A more powerful GPU would unlock higher FPS, especially at higher resolutions and quality presets. GPU-limited at: 1080p high, 1080p low, 1080p medium, 1080p ultra, 1440p high, 1440p low, 1440p medium, 1440p ultra, 4k high, 4k low, 4k medium, 4k ultra.
Yes! Hearts of Iron IV supports AFMF, and your Radeon RX 6400 is compatible with AFMF. With Frame Generation enabled, you can expect a 1.5x-2x FPS multiplier on top of native framerates, significantly boosting perceived smoothness.
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 7 7800X3D and Radeon RX 6400 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.
