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, frame rates range from 23 to 35 FPS depending on quality settings. At 1440p, frame rates range from 21 to 35 FPS. At 4K, frame rates range from 11 to 28 FPS.
The GeForce RTX 4090 is 1051% above the recommended GPU (GeForce GTX 750) for Project Zomboid. The Pentium Dual Core SU4100 is 38% below minimum CPU requirement.
At lower resolutions (1080p (low/medium/high), 1440p (low/medium)), the Pentium Dual Core SU4100 sets the FPS ceiling. As graphical load increases at (1440p ultra, 4k (medium/high/ultra)), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1080p ultra, 1440p high, 4k low.
Approximated average price on current market:
Combo price: $1659. At 1080p Ultra, this combo delivers 23 FPS, equivalent to 0.01 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k ultra, the GeForce RTX 4090 sets the ceiling at about 13 FPS, while the Pentium Dual Core SU4100 has headroom up to 35 FPS. In this scenario, the GPU limits the CPU potential by 63% (FPS gap: 22 FPS). Overall distribution: GPU limits 4/12 cells, CPU limits 5/12, balanced 3/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Pentium Dual Core SU4100 frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 56% | CPU Limits GPU 38% | CPU Limits GPU 20% | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 50% | CPU Limits GPU 27% | Balanced | GPU Limits CPU 26% |
| 4K (Ultra HD) | Balanced | GPU Limits CPU 31% | GPU Limits CPU 51% | GPU Limits CPU 63% |
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.
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 hardware is below minimum requirements. CPU is the limiting factor (38% below minimum). Expect performance issues. Low settings recommended.

The Pentium Dual Core SU4100 and GeForce RTX 4090 will struggle to run Project Zomboid at smooth framerates. At 1080p Ultra, you can expect around 23 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $1659 ($10 CPU + $1649 GPU). 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 7845HX is a great upgrade option (Rank #1 for value).
For Project Zomboid, upgrading the CPU would have the biggest impact on performance. The Pentium Dual Core SU4100 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, 1440p low, 1440p medium. GPU fully utilized at: 1440p ultra, 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 hardware falls below the minimum requirements for this game, which may result in poor 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.
