A deceptively heavy isometric survival game. Its Java-based engine relies heavily on CPU and RAM for zombie AI and simulation. 8GB of RAM is the minimum for late-game scenarios or multiplayer.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 112 FPS. At 1440p, all settings exceed 127 FPS. At 4K, all settings exceed 83 FPS.
The GeForce RTX 4090 is 1051% above the recommended GPU (GeForce GTX 750) for Project Zomboid. The Xeon E-2236 is 117% above the recommended CPU (Core i5-4460).
The Xeon E-2236 determines the performance ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GPU has headroom.
At 4k low, the Xeon E-2236 sets the ceiling at about 149 FPS, while the GeForce RTX 4090 could reach 260 FPS. In this scenario, the CPU limits the GPU potential by 43% (FPS gap: 111 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Xeon E-2236 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 33% | CPU Limits GPU 30% | CPU Limits GPU 26% | CPU Limits GPU 27% |
| 1440p (2K QHD) | CPU Limits GPU 42% | CPU Limits GPU 40% | CPU Limits GPU 26% | CPU Limits GPU 21% |
| 4K (Ultra HD) | CPU Limits GPU 43% | CPU Limits GPU 40% | CPU Limits GPU 22% | CPU Limits GPU 20% |
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.
See how your processor and graphics card compare against the game official minimum and recommended system specs. The placement of your hardware is calculated using relative synthetic performance scores to help you gauge overall playability.
Your CPU is 117% above and your GPU is 1051% above the recommended specs. Ultra settings at 1080p, or High at 1440p/4K.

Yes, the Xeon E-2236 paired with the GeForce RTX 4090 can run Project Zomboid smoothly up to 4k achieving around 83 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 117% 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 Xeon E-2236 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 Xeon E-2236 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.
