This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1440p high, the Ryzen Threadripper 2990WX sets the ceiling at about 193 FPS, while the GeForce RTX 4090 could reach 223 FPS. In this scenario, the CPU limits the GPU potential by 13% (FPS gap: 30 FPS). Overall distribution: CPU limits 10/12 cells, GPU limits 0/12, balanced 2/12.
The Ryzen Threadripper 2990WX and GeForce RTX 4090 stay close in effective frame-generation ceiling across most presets, so neither side consistently suppresses the other by a large margin.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 10% | CPU Limits GPU 11% | CPU Limits GPU 12% | CPU Limits GPU 7% |
| 1440p (2K QHD) | CPU Limits GPU 11% | CPU Limits GPU 12% | CPU Limits GPU 13% | CPU Limits GPU 6% |
| 4K (Ultra HD) | Balanced | CPU Limits GPU 6% | CPU Limits GPU 11% | 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 Ryzen Threadripper 2990WX + GeForce RTX 4090 pairing runs this title with CPU utilization between 25% and 78% and GPU utilization between 4% and 55%. Ryzen Threadripper 2990WX 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 38% at 4K, while CPU averages move from 63% to 46%.
The utilization pattern is relatively even. The GeForce RTX 4090 reaches 40% average at its highest-load preset, while the Ryzen Threadripper 2990WX peaks at 70% 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 63% and GPU 19%. At 1440p, that shifts to CPU 65% and GPU 21%, and at 4K it reaches CPU 46% and GPU 38%. 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 51% (42-60%) and GPU 40% (25-55%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen Threadripper 2990WX remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen Threadripper 2990WX 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 Ryzen Threadripper 2990WX paired with the GeForce RTX 4090 can run Project Zomboid smoothly up to 4k achieving around 101 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 399% above the recommended requirements.
This CPU + GPU combo costs approximately $2896 ($1247 CPU (Rank #390 Value) + $1649 GPU (Rank #77 Value)). Your Ryzen Threadripper 2990WX is currently the main performance bottleneck and its market value ($1247) is actually higher than newer, faster alternatives. Trading it or upgrading could yield immediate profit and performance gains. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #5 for value) while costing less than your current CPU.
For Project Zomboid, upgrading the CPU would have the biggest impact on performance. The Ryzen Threadripper 2990WX 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 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 Ryzen Threadripper 2990WX 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.
