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 Threadripper PRO 5965WX sets the ceiling at about 358 FPS, while the GeForce RTX 4090 could reach 540 FPS. In this scenario, the CPU limits the GPU potential by 34% (FPS gap: 182 FPS). Overall distribution: CPU limits 11/12 cells, GPU limits 0/12, balanced 1/12.
Your Ryzen Threadripper PRO 5965WX 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 34% | CPU Limits GPU 28% | CPU Limits GPU 33% |
| 1440p (2K QHD) | CPU Limits GPU 25% | CPU Limits GPU 21% | CPU Limits GPU 24% | CPU Limits GPU 26% |
| 4K (Ultra HD) | CPU Limits GPU 14% | Balanced | CPU Limits GPU 13% | 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, not generic utilization heuristics.

The Ryzen Threadripper PRO 5965WX + GeForce RTX 4090 pairing runs this title with CPU utilization between 28% and 81% and GPU utilization between 32% and 100%. Ryzen Threadripper PRO 5965WX keeps significant headroom across presets, 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 85% at 4K, while CPU averages move from 51% to 39%.
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 Ryzen Threadripper PRO 5965WX stays at 36% (35-36%). 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 51% and GPU 72%. At 1440p, that shifts to CPU 44% and GPU 79%, and at 4K it reaches CPU 39% and GPU 85%. 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 42% (29-56%) and GPU 88% (75-100%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen Threadripper PRO 5965WX remains stable for consistent frame delivery.
Upgrade priority should be the GPU. The GeForce RTX 4090 reaches 100% average load at 4K (Ultra HD) High while the Ryzen Threadripper PRO 5965WX still has headroom, so a faster graphics card would deliver the largest uplift.
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 Threadripper PRO 5965WX paired with the GeForce RTX 4090 can run Fortnite smoothly up to 4k achieving around 68 FPS at Ultra quality. Your GPU is 136% above the recommended specs, and your CPU is 407% above the recommended requirements.
This CPU + GPU combo costs approximately $1874 ($225 CPU (Rank #319 Value) + $1649 GPU (Rank #77 Value)). Your Ryzen Threadripper PRO 5965WX provides phenomenal top-tier performance but at a premium enthusiast price. Since you are essentially at the ceiling of current hardware capabilities, there are no meaningful performance upgrades available. However, if you wanted a more cost-effective build that still delivers a great experience, you could theoretically step down to a high-end processor with a significantly better value rating. For example, the Ryzen Threadripper PRO 9975WX is a great upgrade option for around $4099 (Rank #329 for value).
Your Ryzen Threadripper PRO 5965WX is already an incredibly powerful processor. While it's technically the first component to hit its limit (which is completely normal in state-of-the-art builds), there is no meaningful upgrade path that would drastically improve your Fortnite performance right now. CPU fully utilized at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 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 Ryzen Threadripper PRO 5965WX 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.
