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, frame rates range from 16 to 33 FPS depending on quality settings. At 1440p, frame rates range from 9 to 33 FPS. At 4K, frame rates range from 4 to 18 FPS.
The GeForce RTX 4090 is 136% above the recommended GPU (GeForce GTX 1080) for Fortnite. The Athlon X2 340 is 79% below minimum CPU requirement.
At lower resolutions (1080p (low/medium/high), 1440p (low/medium)), the Athlon X2 340 sets the FPS ceiling. As graphical load increases at (1440p ultra, 4k (medium/high/ultra)), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1080p ultra, 1440p high, 4k low.
Approximated average price on current market:
Combo price: $1664. At 1080p Ultra, this combo delivers 16 FPS, equivalent to 0.01 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the Athlon X2 340 sets the ceiling at about 33 FPS, while the GeForce RTX 4090 could reach 235 FPS. In this scenario, the CPU limits the GPU potential by 86% (FPS gap: 202 FPS). Overall distribution: CPU limits 5/12 cells, GPU limits 4/12, balanced 3/12.
Your Athlon X2 340 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 86% | CPU Limits GPU 69% | CPU Limits GPU 43% | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 71% | CPU Limits GPU 33% | Balanced | GPU Limits CPU 52% |
| 4K (Ultra HD) | Balanced | GPU Limits CPU 52% | GPU Limits CPU 73% | GPU Limits CPU 85% |
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 Athlon X2 340 and GeForce RTX 4090 will struggle to run Fortnite at smooth framerates. At 1080p Ultra, you can expect around 16 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $1664 ($15 CPU + $1649 GPU). 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 Athlon X2 340 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, 1440p low, 1440p medium. GPU fully utilized at: 1440p ultra, 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 hardware falls below the minimum requirements for this game, which may result in poor 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.
