Performance Report
At 1080p, all quality settings exceed 121 FPS. At 1440p, all settings exceed 122 FPS. At 4K, all settings exceed 90 FPS.
The GeForce RTX 4090 is 1051% above the recommended GPU (GeForce GTX 750) for Project Zomboid. The Ryzen 9 7940HS is 368% above the recommended CPU (Core i5-4460).
The Ryzen 9 7940HS determines the performance ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GPU has headroom.
At 1440p low, the Ryzen 9 7940HS sets the ceiling at about 191 FPS, while the GeForce RTX 4090 could reach 339 FPS. In this scenario, the CPU limits the GPU potential by 44% (FPS gap: 148 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Ryzen 9 7940HS 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 37% | CPU Limits GPU 34% | CPU Limits GPU 29% | CPU Limits GPU 21% |
| 1440p (2K QHD) | CPU Limits GPU 44% | CPU Limits GPU 43% | CPU Limits GPU 33% | CPU Limits GPU 20% |
| 4K (Ultra HD) | CPU Limits GPU 36% | CPU Limits GPU 33% | CPU Limits GPU 21% | CPU Limits GPU 9% |
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.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

The Ryzen 9 7940HS + GeForce RTX 4090 pairing runs this title with CPU utilization between 7% and 62% and GPU utilization between 17% and 84%. Ryzen 9 7940HS keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 38% at 1080p to 61% at 4K, while CPU averages move from 44% to 27%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 76% average at its highest-load preset, while the Ryzen 9 7940HS peaks at 48% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 44% and GPU 38%. At 1440p, that shifts to CPU 42% and GPU 38%, and at 4K it reaches CPU 27% and GPU 61%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
4K (Ultra HD) High is the most balanced preset based on this dataset. It runs around CPU 12% (7-17%) and GPU 76% (68-84%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen 9 7940HS remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 9 7940HS and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization & Bottlenecks: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. This is the key to identifying performance bottlenecks in any system.

Yes, the Ryzen 9 7940HS paired with the GeForce RTX 4090 can run Project Zomboid smoothly up to 4k achieving around 90 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 368% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For Project Zomboid, upgrading the CPU would have the biggest impact on performance. The Ryzen 9 7940HS 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 Ryzen 9 7940HS 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.
