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 148 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 115 FPS. At 4K, all settings exceed 75 FPS.
The GeForce RTX 4090 is 136% above the recommended GPU (GeForce GTX 1080) for Fortnite. The Core i5-14400 is 93% above the recommended CPU (Core i5-7300U).
The Core i5-14400 sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GeForce RTX 4090 still has headroom.
Approximated average price on current market:
Combo price: $1846. At 1080p Ultra, this combo delivers 148 FPS, equivalent to 0.08 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages. Adjacent heavier settings are lightly stabilized to remove prediction jitter that would otherwise create impossible reversals.
At 1080p low, the Core i5-14400 sets the ceiling at about 633 FPS, while the GeForce RTX 4090 could reach 953 FPS. In this scenario, the CPU limits the GPU potential by 34% (FPS gap: 320 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core i5-14400 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 34% | CPU Limits GPU 17% | CPU Limits GPU 17% | CPU Limits GPU 17% |
| 1440p (2K QHD) | CPU Limits GPU 15% | CPU Limits GPU 15% | CPU Limits GPU 15% | CPU Limits GPU 15% |
| 4K (Ultra HD) | CPU Limits GPU 14% | CPU Limits GPU 12% | CPU Limits GPU 12% | CPU Limits GPU 10% |
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 and then monotonic-smoothed across heavier presets and resolutions, not generic utilization heuristics.

Yes, the Core i5-14400 paired with the GeForce RTX 4090 can run Fortnite smoothly up to 4k achieving around 75 FPS at Ultra quality. Your GPU is 136% above the recommended specs, and your CPU is 93% above the recommended requirements.
This CPU + GPU combo costs approximately $1846 ($197 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 9950X is a great upgrade option for around $649 (Rank #4 for value).
For Fortnite, upgrading the CPU would have the biggest impact on performance. The Core i5-14400 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.
Fortnite 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.
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 Core i5-14400 and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
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.
