This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k low, the Core i5-4670K sets the ceiling at about 99 FPS, while the GeForce RTX 4090 could reach 248 FPS. In this scenario, the CPU limits the GPU potential by 60% (FPS gap: 149 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core i5-4670K 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 51% | CPU Limits GPU 50% | CPU Limits GPU 46% | CPU Limits GPU 49% |
| 1440p (2K QHD) | CPU Limits GPU 57% | CPU Limits GPU 56% | CPU Limits GPU 42% | CPU Limits GPU 41% |
| 4K (Ultra HD) | CPU Limits GPU 60% | CPU Limits GPU 59% | CPU Limits GPU 47% | CPU Limits GPU 42% |
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 Core i5-4670K + GeForce RTX 4090 pairing runs this title with CPU utilization between 32% and 92% and GPU utilization between 0% and 54%. Core i5-4670K stays in a controlled operating range, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 19% at 1080p to 29% at 4K, while CPU averages move from 75% to 59%.
The utilization pattern is relatively even. The GeForce RTX 4090 reaches 38% average at its highest-load preset, while the Core i5-4670K peaks at 80% 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 75% and GPU 19%. At 1440p, that shifts to CPU 75% and GPU 21%, and at 4K it reaches CPU 59% and GPU 29%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
1440p (2K QHD) Ultra is the most balanced preset based on this dataset. It runs around CPU 70% (56-84%) and GPU 38% (22-53%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i5-4670K remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core i5-4670K 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 Core i5-4670K paired with the GeForce RTX 4090 can run Project Zomboid smoothly up to 4k achieving around 61 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 13% below the recommended requirements.
This CPU + GPU combo costs approximately $1849 ($200 CPU + $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 Project Zomboid, upgrading the CPU would have the biggest impact on performance. The Core i5-4670K 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: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
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 setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
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.
