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, frame rates range from 19 to 40 FPS depending on quality settings. At 1440p, frame rates range from 10 to 21 FPS. At 4K, frame rates range from 9 to 19 FPS.
The GeForce RTX 4090 is 870% above the recommended GPU (GeForce GTX 570) for Hearts of Iron IV. The Celeron 4305UE is 53% below minimum CPU requirement.
The GeForce RTX 4090 sets the FPS ceiling at 1080p (medium/high/ultra), all 1440p settings, all 4k settings, while the Celeron 4305UE still has additional frame-generation headroom. The FPS ceiling is closely matched at 1080p low.
Approximated average price on current market:
Combo price: $1756. At 1080p Ultra, this combo delivers 19 FPS, equivalent to 0.01 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k ultra, the GeForce RTX 4090 sets the ceiling at about 11 FPS, while the Celeron 4305UE has headroom up to 42 FPS. In this scenario, the GPU limits the CPU potential by 74% (FPS gap: 31 FPS). Overall distribution: GPU limits 11/12 cells, CPU limits 0/12, balanced 1/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Celeron 4305UE frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | Balanced | GPU Limits CPU 33% | GPU Limits CPU 38% | GPU Limits CPU 48% |
| 1440p (2K QHD) | GPU Limits CPU 45% | GPU Limits CPU 62% | GPU Limits CPU 67% | GPU Limits CPU 69% |
| 4K (Ultra HD) | GPU Limits CPU 45% | GPU Limits CPU 64% | GPU Limits CPU 67% | GPU Limits CPU 74% |
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 Celeron 4305UE and GeForce RTX 4090 will struggle to run Hearts of Iron IV at smooth framerates. At 1080p Ultra, you can expect around 19 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $1756 ($107 CPU + $1649 GPU). 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 medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
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 hardware falls below the minimum requirements for this game, which may result in poor performance.
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.
