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 85 FPS. At 1440p, all settings exceed 61 FPS. At 4K, frame rates range from 41 to 80 FPS.
The GeForce RTX 4090 is 136% above the recommended GPU (GeForce GTX 1080) for Fortnite. The Core i5-10400T is 26% below recommended, but 53% above minimum.
The Core i5-10400T 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: $1749. At 1080p Ultra, this combo delivers 85 FPS, equivalent to 0.05 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1440p low, the Core i5-10400T sets the ceiling at about 134 FPS, while the GeForce RTX 4090 could reach 377 FPS. In this scenario, the CPU limits the GPU potential by 64% (FPS gap: 243 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core i5-10400T 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 59% | CPU Limits GPU 52% | CPU Limits GPU 46% | CPU Limits GPU 56% |
| 1440p (2K QHD) | CPU Limits GPU 64% | CPU Limits GPU 56% | CPU Limits GPU 59% | CPU Limits GPU 59% |
| 4K (Ultra HD) | CPU Limits GPU 60% | CPU Limits GPU 48% | CPU Limits GPU 55% | CPU Limits GPU 50% |
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.

Yes, the Core i5-10400T paired with the GeForce RTX 4090 can run Fortnite smoothly up to 1440p achieving around 61 FPS at Ultra quality. Your GPU is 136% above the recommended specs, and your CPU is 26% below the recommended requirements.
This CPU + GPU combo costs approximately $1749 ($100 CPU (Rank #190 Value) + $1649 GPU (Rank #77 Value)). 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 #5 for value).
For Fortnite, upgrading the CPU would have the biggest impact on performance. The Core i5-10400T 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 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.
