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 Ryzen 5 4600G sets the ceiling at about 294 FPS, while the GeForce RTX 4090 could reach 556 FPS. In this scenario, the CPU limits the GPU potential by 47% (FPS gap: 262 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Ryzen 5 4600G 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 47% | CPU Limits GPU 37% | CPU Limits GPU 29% | CPU Limits GPU 36% |
| 1440p (2K QHD) | CPU Limits GPU 41% | CPU Limits GPU 28% | CPU Limits GPU 29% | CPU Limits GPU 37% |
| 4K (Ultra HD) | CPU Limits GPU 24% | CPU Limits GPU 8% | CPU Limits GPU 16% | CPU Limits GPU 21% |
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 5 4600G + GeForce RTX 4090 pairing runs this title with CPU utilization between 29% and 95% and GPU utilization between 28% and 98%. Ryzen 5 4600G 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 71% at 1080p to 82% at 4K, while CPU averages move from 63% to 62%.
From a utilization perspective, this is a GPU-heavy load profile. At 4K (Ultra HD) High, the GeForce RTX 4090 averages 98% usage (97-98%), while the Ryzen 5 4600G stays at 48% (37-60%). 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 71%. At 1440p, that shifts to CPU 61% and GPU 81%, and at 4K it reaches CPU 62% and GPU 82%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
1080p (Full HD) High is the most balanced preset based on this dataset. It runs around CPU 49% (36-62%) and GPU 86% (78-94%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen 5 4600G remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 5 4600G 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 Ryzen 5 4600G paired with the GeForce RTX 4090 can run Fortnite smoothly up to 4k achieving around 65 FPS at Ultra quality. Your GPU is 136% above the recommended specs, and your CPU is 22% above the recommended requirements.
This CPU + GPU combo costs approximately $1792 ($143 CPU (Rank #154 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 Ryzen 5 4600G 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 high, 1080p low, 1080p medium, 1080p ultra, 1440p high, 1440p low, 1440p medium, 1440p ultra, 4k high, 4k low, 4k medium, 4k ultra.
Yes! Fortnite supports DLSS Frame Gen and AFMF, and your GeForce RTX 4090 is compatible with DLSS Frame Gen. With Frame Generation enabled, you can expect a 2x-3x FPS multiplier on top of native framerates, significantly boosting perceived smoothness.
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 Ryzen 5 4600G 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.
