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.
This CPU/GPU pair is mostly balanced in Fortnite. Across tested presets: GPU limits in 0/12, CPU limits in 0/12, and balanced in 12/12. Peak observed performance in the sampled cells is around 563 FPS.
The Ryzen Threadripper PRO 7975WX and GeForce RTX 4090 stay close in effective frame-generation ceiling across most presets, so neither side consistently suppresses the other by a large margin.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | Balanced | Balanced | Balanced | Balanced |
| 1440p (2K QHD) | Balanced | Balanced | Balanced | Balanced |
| 4K (Ultra HD) | Balanced | Balanced | Balanced | Balanced |
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 7975WX + GeForce RTX 4090 pairing runs this title with CPU utilization between 19% and 99% and GPU utilization between 29% and 100%. Ryzen Threadripper PRO 7975WX 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 71% at 1080p to 84% at 4K, while CPU averages move from 65% to 49%.
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 7975WX stays at 24% (21-26%). 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 65% and GPU 71%. At 1440p, that shifts to CPU 54% and GPU 78%, and at 4K it reaches CPU 49% 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 72% (72-73%) and GPU 86% (75-98%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen Threadripper PRO 7975WX remains stable for consistent frame delivery.
Both components are stressed near their limits in the heaviest presets (Ryzen Threadripper PRO 7975WX: 92% 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 Ryzen Threadripper PRO 7975WX paired with the GeForce RTX 4090 can run Fortnite smoothly up to 4k achieving around 81 FPS at Ultra quality. Your GPU is 136% above the recommended specs, and your CPU is 629% above the recommended requirements.
This CPU + GPU combo costs approximately $5620.7 ($3971.7 CPU (Rank #342 Value) + $1649 GPU (Rank #77 Value)). This is a well-balanced setup, meaning you're getting good value from both components without significant waste.
This setup is already well-balanced for Fortnite. No significant bottleneck - CPU and GPU are well matched across all settings. Both the Ryzen Threadripper PRO 7975WX and GeForce RTX 4090 complement each other effectively, so upgrading either component individually would yield diminishing returns. If you want more FPS, you'd benefit most from upgrading both CPU and GPU together.
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 7975WX 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.
