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 139 FPS. At 1440p, all settings exceed 101 FPS. At 4K, all settings exceed 62 FPS.
The GeForce RTX 4090 is 136% above the recommended GPU (GeForce GTX 1080) for Fortnite. The Core Ultra 7 265U is 36% above the recommended CPU (Core i5-7300U).
The Core Ultra 7 265U sets the FPS ceiling at 1080p (low/ultra), all 1440p settings, all 4k settings, while the GeForce RTX 4090 still has headroom. The FPS ceiling is closely matched at 1080p (medium/high).
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1440p low, the Core Ultra 7 265U sets the ceiling at about 249 FPS, while the GeForce RTX 4090 could reach 377 FPS. In this scenario, the CPU limits the GPU potential by 34% (FPS gap: 128 FPS). Overall distribution: CPU limits 10/12 cells, GPU limits 0/12, balanced 2/12.
Your Core Ultra 7 265U 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 20% | Balanced | Balanced | CPU Limits GPU 26% |
| 1440p (2K QHD) | CPU Limits GPU 34% | CPU Limits GPU 25% | CPU Limits GPU 24% | CPU Limits GPU 29% |
| 4K (Ultra HD) | CPU Limits GPU 31% | CPU Limits GPU 25% | CPU Limits GPU 23% | CPU Limits GPU 23% |
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 Ultra 7 265U + GeForce RTX 4090 pairing runs this title with CPU utilization between 12% and 97% and GPU utilization between 26% and 100%. Core Ultra 7 265U reaches high load in heavier scenarios, while GeForce RTX 4090 carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 67% at 1080p to 84% at 4K, while CPU averages move from 63% to 55%.
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 Ultra 7 265U stays at 32% (16-47%). 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 63% and GPU 67%. At 1440p, that shifts to CPU 59% and GPU 82%, and at 4K it reaches CPU 55% and GPU 84%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
4K (Ultra HD) Medium is the most balanced preset based on this dataset. It runs around CPU 75% (74-76%) and GPU 86% (77-95%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core Ultra 7 265U remains stable for consistent frame delivery.
Both components are stressed near their limits in the heaviest presets (Core Ultra 7 265U: 90% avg, GeForce RTX 4090: 100% avg). A targeted upgrade should follow your target resolution: GPU first for higher image quality, CPU first for higher minimum FPS.
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 Ultra 7 265U 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 36% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For Fortnite, upgrading the CPU would have the biggest impact on performance. The Core Ultra 7 265U 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 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 Ultra 7 265U 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.
