This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1440p low, the EPYC 9374F sets the ceiling at about 217 FPS, while the GeForce RTX 4090 could reach 326 FPS. In this scenario, the CPU limits the GPU potential by 33% (FPS gap: 109 FPS). Overall distribution: CPU limits 11/12 cells, GPU limits 0/12, balanced 1/12.
Your EPYC 9374F is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 29% | CPU Limits GPU 25% | CPU Limits GPU 19% | CPU Limits GPU 14% |
| 1440p (2K QHD) | CPU Limits GPU 33% | CPU Limits GPU 31% | CPU Limits GPU 22% | CPU Limits GPU 13% |
| 4K (Ultra HD) | CPU Limits GPU 20% | CPU Limits GPU 18% | CPU Limits GPU 14% | 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.

The EPYC 9374F + GeForce RTX 4090 pairing runs this title with CPU utilization between 7% and 72% and GPU utilization between 4% and 51%. EPYC 9374F keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 18% at 1080p to 35% at 4K, while CPU averages move from 50% to 37%.
The utilization pattern is relatively even. The GeForce RTX 4090 reaches 37% average at its highest-load preset, while the EPYC 9374F peaks at 54% average. This suggests a fairly controlled load distribution, but the actual FPS-limiting side should still be read from the limiter analysis above.
At 1080p, averages sit around CPU 50% and GPU 18%. At 1440p, that shifts to CPU 52% and GPU 20%, and at 4K it reaches CPU 37% and GPU 35%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
4K (Ultra HD) Low is the most balanced preset based on this dataset. It runs around CPU 40% (35-44%) and GPU 37% (23-51%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 9374F remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 9374F and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

Yes, the EPYC 9374F paired with the GeForce RTX 4090 can run Project Zomboid smoothly up to 4k achieving around 100 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 1180% above the recommended requirements.
This CPU + GPU combo costs approximately $5115 ($3466 CPU (Rank #392 Value) + $1649 GPU (Rank #77 Value)). Your EPYC 9374F 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 EPYC 9455P is a great upgrade option for around $4819 (Rank #344 for value).
Your EPYC 9374F 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 Project Zomboid performance right now. CPU fully utilized at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high.
Project Zomboid 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.
Project Zomboid requires at minimum a Core 2 Quad Q6600 (CPU) and GeForce 6600 (GPU) with 8 GB RAM and 5 GB storage. For the recommended experience, you need a Core i5-4460 and GeForce GTX 750 with 8 GB RAM. Your EPYC 9374F and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Project Zomboid 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.
