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, frame rates range from 32 to 202 FPS depending on quality settings. At 1440p, frame rates range from 19 to 102 FPS. At 4K, frame rates range from 7 to 39 FPS.
The GeForce GTX 770 is 3% below minimum GPU requirement for Fortnite. The Ryzen 7 7800X3D is 161% above the recommended CPU (Core i5-7300U).
Fortnite supports: DLSS Frame Gen, AFMF. However, the GeForce GTX 770 is not compatible with these technologies.
The GeForce GTX 770 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: $424. At 1080p Ultra, this combo delivers 32 FPS, equivalent to 0.08 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k ultra, the GeForce GTX 770 sets the ceiling at about 7 FPS, while the Ryzen 7 7800X3D has headroom up to 74 FPS. In this scenario, the GPU limits the CPU potential by 91% (FPS gap: 67 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your GeForce GTX 770 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 66% | GPU Limits CPU 78% | GPU Limits CPU 77% | GPU Limits CPU 85% |
| 1440p (2K QHD) | GPU Limits CPU 72% | GPU Limits CPU 82% | GPU Limits CPU 84% | GPU Limits CPU 86% |
| 4K (Ultra HD) | GPU Limits CPU 79% | GPU Limits CPU 86% | GPU Limits CPU 90% | GPU Limits CPU 91% |
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.

The Ryzen 7 7800X3D and GeForce GTX 770 will struggle to run Fortnite at smooth framerates. At 1080p Ultra, you can expect around 32 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $424 ($384 CPU (Rank #212 Value) + $40 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 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 GeForce GTX 770 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 GeForce GTX 770 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 hardware falls below the minimum requirements for this game, which may result in poor 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.
