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 15 to 29 FPS depending on quality settings. At 1440p, frame rates range from 11 to 22 FPS. At 4K, frame rates range from 7 to 15 FPS.
The Radeon HD 7520G + HD 8750M Dual is 57% below minimum GPU requirement for Project Zomboid. The Ryzen 7 7800X3D is 435% above the recommended CPU (Core i5-4460).
The Radeon HD 7520G + HD 8750M Dual sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Ryzen 7 7800X3D still has additional frame-generation headroom.
Approximated average price on current market:
Combo price: $534. At 1080p Ultra, this combo delivers 15 FPS, equivalent to 0.03 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k low, the Radeon HD 7520G + HD 8750M Dual sets the ceiling at about 15 FPS, while the Ryzen 7 7800X3D has headroom up to 158 FPS. In this scenario, the GPU limits the CPU potential by 91% (FPS gap: 143 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your Radeon HD 7520G + HD 8750M Dual is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 7800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 86% | GPU Limits CPU 87% | GPU Limits CPU 84% | GPU Limits CPU 87% |
| 1440p (2K QHD) | GPU Limits CPU 89% | GPU Limits CPU 89% | GPU Limits CPU 88% | GPU Limits CPU 90% |
| 4K (Ultra HD) | GPU Limits CPU 91% | GPU Limits CPU 90% | GPU Limits CPU 89% | GPU Limits CPU 90% |
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. GPU is the limiting factor (57% below minimum). Expect performance issues. Low settings recommended.

The Ryzen 7 7800X3D and Radeon HD 7520G + HD 8750M Dual will struggle to run Project Zomboid at smooth framerates. At 1080p Ultra, you can expect around 15 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $534 ($384 CPU + $150 GPU). Since the GPU is the main limiting factor, investing in a stronger GPU will improve your framerates and overall value. For example, upgrading to the GeForce GTX 1080 SLI (móvel) (Rank #2 for value) could deliver noticeably better performance.
For Project Zomboid, upgrading the GPU would give you the most noticeable improvement. The Radeon HD 7520G + HD 8750M Dual is the limiting factor here, while the Ryzen 7 7800X3D still has spare capacity. A more powerful GPU would unlock higher FPS, especially at higher resolutions and quality presets. GPU-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 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.
