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 143 FPS. At 1440p, all settings exceed 84 FPS. At 4K, frame rates range from 54 to 155 FPS.
The GeForce RTX 4090 is 870% above the recommended GPU (GeForce GTX 570) for Hearts of Iron IV. The Ryzen Threadripper 1920 is 767% 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 (1440p (medium/ultra), all 4k settings), the Ryzen Threadripper 1920 sets the FPS ceiling. As graphical load increases at (all 1080p settings), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1440p (low/high).
Approximated average price on current market:
Combo price: $1849. At 1080p Ultra, this combo delivers 143 FPS, equivalent to 0.08 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 207 FPS, while the Ryzen Threadripper 1920 has headroom up to 367 FPS. In this scenario, the GPU limits the CPU potential by 44% (FPS gap: 160 FPS). Overall distribution: GPU limits 4/12 cells, CPU limits 7/12, balanced 1/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Ryzen Threadripper 1920 frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 44% | GPU Limits CPU 40% | GPU Limits CPU 40% | GPU Limits CPU 24% |
| 1440p (2K QHD) | Balanced | CPU Limits GPU 7% | CPU Limits GPU 6% | CPU Limits GPU 18% |
| 4K (Ultra HD) | CPU Limits GPU 23% | CPU Limits GPU 29% | CPU Limits GPU 25% | CPU Limits GPU 35% |
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 Threadripper 1920 paired with the GeForce RTX 4090 can run Hearts of Iron IV smoothly up to 1440p achieving around 84 FPS at Ultra quality. Your GPU is 870% above the recommended specs, and your CPU is 767% above the recommended requirements.
This CPU + GPU combo costs approximately $1849 ($200 CPU (Rank #283 Value) + $1649 GPU (Rank #77 Value)). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #5 for value).
For Hearts of Iron IV, upgrading the CPU would have the biggest impact on performance. The Ryzen Threadripper 1920 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: 1440p medium, 1440p ultra, 4k high, 4k low, 4k medium, 4k ultra. GPU fully utilized at: 1080p high, 1080p low, 1080p medium, 1080p 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 Threadripper 1920 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.
