Performance Report
At 1080p, all quality settings exceed 133 FPS. At 1440p, all settings exceed 107 FPS. At 4K, all settings exceed 68 FPS.
The GeForce RTX 4090 is 870% above the recommended GPU (GeForce GTX 570) for Hearts of Iron IV. The Ryzen 5 PRO 5655GE is 614% 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.
At lower resolutions (all 4k settings), the Ryzen 5 PRO 5655GE sets the FPS ceiling. As graphical load increases at (all 1080p settings, all 1440p settings), the GeForce RTX 4090 becomes the FPS-limiting side.
Approximated average price on current market:
Combo price: $1795. At 1080p Ultra, this combo delivers 133 FPS, equivalent to 0.07 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the GeForce RTX 4090 sets the ceiling at about 123 FPS, while the Ryzen 5 PRO 5655GE has headroom up to 242 FPS. In this scenario, the GPU limits the CPU potential by 49% (FPS gap: 119 FPS). Overall distribution: GPU limits 8/12 cells, CPU limits 4/12, balanced 0/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Ryzen 5 PRO 5655GE frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 49% | GPU Limits CPU 49% | GPU Limits CPU 49% | GPU Limits CPU 43% |
| 1440p (2K QHD) | GPU Limits CPU 25% | GPU Limits CPU 22% | GPU Limits CPU 25% | GPU Limits CPU 17% |
| 4K (Ultra HD) | CPU Limits GPU 10% | CPU Limits GPU 13% | CPU Limits GPU 10% | CPU Limits GPU 18% |
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 5 PRO 5655GE paired with the GeForce RTX 4090 can run Hearts of Iron IV smoothly up to 4k achieving around 68 FPS at Ultra quality. Your GPU is 870% above the recommended specs, and your CPU is 614% above the recommended requirements.
This CPU + GPU combo costs approximately $1795 ($146 CPU (Rank #116 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 high, 1080p low, 1080p medium, 1080p ultra, 1440p high, 1440p low, 1440p medium, 1440p ultra. CPU-limited at: 4k high, 4k low, 4k medium, 4k ultra.
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 5 PRO 5655GE 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.
