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

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the Core 5 120UL sets the ceiling at about 264 FPS, while the GeForce RTX 4090 could reach 556 FPS. In this scenario, the CPU limits the GPU potential by 53% (FPS gap: 292 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core 5 120UL 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 53% | CPU Limits GPU 32% | CPU Limits GPU 8% | CPU Limits GPU 32% |
| 1440p (2K QHD) | CPU Limits GPU 38% | CPU Limits GPU 25% | CPU Limits GPU 26% | CPU Limits GPU 31% |
| 4K (Ultra HD) | CPU Limits GPU 35% | CPU Limits GPU 23% | CPU Limits GPU 22% | CPU Limits GPU 24% |
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 Core 5 120UL + GeForce RTX 4090 pairing runs this title with CPU utilization between 14% and 92% and GPU utilization between 33% and 100%. Core 5 120UL stays in a controlled operating range, while GeForce RTX 4090 carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 72% at 1080p to 84% at 4K, while CPU averages move from 57% to 47%.
From a utilization perspective, this is a GPU-heavy load profile. At 4K (Ultra HD) High, the GeForce RTX 4090 averages 100% usage (100-100%), while the Core 5 120UL stays at 34% (17-51%). This shows the graphics pipeline is carrying most of the workload, but utilization alone does not define the FPS limiter.
At 1080p, averages sit around CPU 57% and GPU 72%. At 1440p, that shifts to CPU 49% and GPU 82%, and at 4K it reaches CPU 47% and GPU 84%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
1080p (Full HD) High is the most balanced preset based on this dataset. It runs around CPU 43% (24-62%) and GPU 86% (75-96%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core 5 120UL remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core 5 120UL and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

Yes, the Core 5 120UL paired with the GeForce RTX 4090 can run Fortnite smoothly up to 4k achieving around 62 FPS at Ultra quality. Your GPU is 136% above the recommended specs, and your CPU is 20% below the recommended requirements.
This CPU + GPU combo costs approximately $1919 ($270 CPU (Rank #371 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 5 120UL 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.
