Fortnite serves as a showcase for Unreal Engine 5. In 'Performance Mode', it runs on almost anything. However, enabling 'Lumen' (global illumination) and 'Nanite' (virtualized geometry) requires a powerful RTX 30/40 series GPU to maintain 60 FPS. The building mechanics also add a significant CPU load, especially in competitive end-games with dense player structures.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 131 FPS. At 1440p, all settings exceed 85 FPS. At 4K, frame rates range from 40 to 108 FPS.
The Arc B580 is 1% below recommended, but 161% above minimum for Fortnite. The Ryzen 7 7800X3D is 161% above the recommended CPU (Core i5-7300U).
Fortnite supports: DLSS Frame Gen, AFMF. However, the Arc B580 is not compatible with these technologies.
The Arc B580 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: $633. At 1080p Ultra, this combo delivers 131 FPS, equivalent to 0.21 FPS per dollar.
| Resolution | Low | Medium | High | Ultra |

| 1080p | 0.622 fps/$ | 0.460 fps/$ | 0.316 fps/$ | 0.207 fps/$ |
| 1440p | 0.385 fps/$ | 0.259 fps/$ | 0.196 fps/$ | 0.134 fps/$ |

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k high, the Arc B580 sets the ceiling at about 54 FPS, while the Ryzen 7 7800X3D has headroom up to 116 FPS. In this scenario, the GPU limits the CPU potential by 53% (FPS gap: 62 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your Arc B580 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 32% | GPU Limits CPU 38% | GPU Limits CPU 14% | GPU Limits CPU 31% |
| 1440p (2K QHD) | GPU Limits CPU 36% | GPU Limits CPU 41% | GPU Limits CPU 34% | GPU Limits CPU 37% |
| 4K (Ultra HD) | GPU Limits CPU 45% | GPU Limits CPU 49% | GPU Limits CPU 53% | GPU Limits CPU 47% |
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 161% below recommended and your GPU is 1% below recommended, but both meet minimum specs. Playable at Low/Medium settings, 1080p or below.

Yes, the Ryzen 7 7800X3D paired with the Arc B580 can run Fortnite smoothly up to 1440p achieving around 85 FPS at Ultra quality. Your GPU is 1% below the recommended specs, and your CPU is 161% above the recommended requirements.
This CPU + GPU combo costs approximately $633 ($384 CPU (Rank #212 Value) + $249 GPU (Rank #14 Value)). Your build is already very cost-efficient, but if you want even more FPS, the next good option is upgrading the GPU. For example, upgrading to the GeForce RTX 5060 for around $299 (Rank #2 for value) could deliver noticeably better performance.
For Fortnite, upgrading the GPU would give you the most noticeable improvement. The Arc B580 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 high, 1080p low, 1080p medium, 1080p ultra, 1440p high, 1440p low, 1440p medium, 1440p ultra, 4k high, 4k low, 4k medium, 4k ultra.
Fortnite supports DLSS Frame Gen and AFMF, but your Arc B580 is not compatible with all of them. Frame Generation is typically available on newer GPUs like the RTX 40-series (DLSS 3) or modern AMD cards (FSR 3).
Fortnite requires at minimum a Core i3-3225 (CPU) and GeForce GTX 960 (GPU) with 8 GB RAM and 30 GB storage. For the recommended experience, you need a Core i5-7300U and GeForce GTX 1080 with 16 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 Fortnite 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.
