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 75 FPS. At 1440p, all settings exceed 75 FPS. At 4K, all settings exceed 75 FPS.
The GeForce RTX 4090 is 1051% above the recommended GPU (GeForce GTX 750) for Project Zomboid. The A8 PRO-7600B is 53% below recommended, but 32% above minimum.
The A8 PRO-7600B sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GeForce RTX 4090 still has headroom.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1440p low, the A8 PRO-7600B sets the ceiling at about 75 FPS, while the GeForce RTX 4090 could reach 341 FPS. In this scenario, the CPU limits the GPU potential by 78% (FPS gap: 266 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your A8 PRO-7600B 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 74% | CPU Limits GPU 70% | CPU Limits GPU 60% | CPU Limits GPU 52% |
| 1440p (2K QHD) | CPU Limits GPU 78% | CPU Limits GPU 75% | CPU Limits GPU 64% | CPU Limits GPU 53% |
| 4K (Ultra HD) | CPU Limits GPU 69% | CPU Limits GPU 63% | CPU Limits GPU 48% | CPU Limits GPU 25% |
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 CPU is 53% below recommended and your GPU is 1051% below recommended, but both meet minimum specs. Playable at Low/Medium settings, 1080p or below.

Yes, the A8 PRO-7600B paired with the GeForce RTX 4090 can run Project Zomboid smoothly up to 4k achieving around 75 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 53% below 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 A8 PRO-7600B 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.
