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 75 FPS. At 1440p, all settings exceed 92 FPS. At 4K, all settings exceed 86 FPS.
The GeForce RTX 4090 is 870% above the recommended GPU (GeForce GTX 570) for Hearts of Iron IV. The Ryzen 7 9800X3D is 1470% above the recommended CPU (Core i5-750).
Hearts of Iron IV supports: AFMF. This game does not have native DLSS 3 or FSR 3 Frame Generation support. AFMF is AMD-exclusive and not compatible with GeForce RTX 4090.
The Ryzen 7 9800X3D sets the FPS ceiling at 1080p low, 4k low, while the GeForce RTX 4090 still has headroom. The FPS ceiling is closely matched at 1080p (medium/high/ultra), all 1440p settings, 4k (medium/high/ultra).
Approximated average price on current market:
Combo price: $2128. At 1080p Ultra, this combo delivers 75 FPS, equivalent to 0.04 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the Ryzen 7 9800X3D sets the ceiling at about 110 FPS, while the GeForce RTX 4090 could reach 120 FPS. In this scenario, the CPU limits the GPU potential by 8% (FPS gap: 10 FPS). Overall distribution: CPU limits 2/12 cells, GPU limits 1/12, balanced 9/12.
The Ryzen 7 9800X3D and GeForce RTX 4090 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% | Balanced | Balanced | Balanced |
| 1440p (2K QHD) | Balanced | Balanced | GPU Limits CPU 7% | Balanced |
| 4K (Ultra HD) | CPU Limits GPU 7% | 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, not generic utilization heuristics.

Yes, the Ryzen 7 9800X3D paired with the GeForce RTX 4090 can run Hearts of Iron IV smoothly up to 4k achieving around 86 FPS at Ultra quality. Your GPU is 870% above the recommended specs, and your CPU is 1470% above the recommended requirements.
This CPU + GPU combo costs approximately $2128 ($479 CPU (Rank #234 Value) + $1649 GPU (Rank #77 Value)). Your Ryzen 7 9800X3D 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 #5 for value).
Your Ryzen 7 9800X3D 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, 4k low.
Hearts of Iron IV currently only supports AFMF (AMD Fluid Motion Frames) for frame generation, which is an AMD-exclusive technology. Because you are using an NVIDIA GPU, you cannot use Frame Generation for this specific game.
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 9800X3D 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.
