As the world's most popular MOBA, League of Legends runs on a proprietary engine that has been updated for over a decade. Recently, Riot increased the minimum requirements to include AVX instruction support and dropped support for older OSs and DirectX 9. While still lightweight, modern team fights with complex particle effects can strain older integrated graphics. The game scales well with single-thread CPU performance, meaning even modern entry-level processors can deliver high frame rates.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 618 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 532 FPS. At 4K, all settings exceed 289 FPS.
The GeForce RTX 5090 is 1304% above the recommended GPU (GeForce GTX 560) for League of Legends. The Xeon E5-2699 v4 is 286% above the recommended CPU (Core i5-3330).
At lower resolutions (1080p (low/medium), 1440p low, all 4k settings), the Xeon E5-2699 v4 sets the FPS ceiling. As graphical load increases at (1080p ultra, 1440p (high/ultra)), the GeForce RTX 5090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1080p high, 1440p medium.
Approximated average price on current market:
Combo price: $3100. At 1080p Ultra, this combo delivers 618 FPS, equivalent to 0.2 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages. Adjacent heavier settings are lightly stabilized to remove prediction jitter that would otherwise create impossible reversals.
At 1080p low, the Xeon E5-2699 v4 sets the ceiling at about 618 FPS, while the GeForce RTX 5090 could reach 824 FPS. In this scenario, the CPU limits the GPU potential by 25% (FPS gap: 206 FPS). Overall distribution: CPU limits 4/12 cells, GPU limits 5/12, balanced 3/12.
Your Xeon E5-2699 v4 is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 5090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 25% | CPU Limits GPU 10% | Balanced | GPU Limits CPU 16% |
| 1440p (2K QHD) | CPU Limits GPU 15% | Balanced | GPU Limits CPU 11% | GPU Limits CPU 17% |
| 4K (Ultra HD) | CPU Limits GPU 8% | Balanced | GPU Limits CPU 11% | GPU Limits CPU 17% |
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 and then monotonic-smoothed across heavier presets and resolutions, not generic utilization heuristics.

Yes, the Xeon E5-2699 v4 paired with the GeForce RTX 5090 can run League of Legends smoothly up to 4k achieving around 289 FPS at Ultra quality. Your GPU is 1304% above the recommended specs, and your CPU is 286% above the recommended requirements.
This CPU + GPU combo costs approximately $3100 ($400 CPU + $2700 GPU). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the EPYC 9375F is a great upgrade option for around $5306 (Rank #5 for value).
For League of Legends, upgrading the CPU would have the biggest impact on performance. The Xeon E5-2699 v4 is currently the limiting factor — the GeForce RTX 5090 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, 1440p low, 4k low, 4k medium, 4k high, 4k ultra. GPU fully utilized at: 1080p ultra, 1440p high, 1440p ultra.
League of Legends 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.
League of Legends requires at minimum a Core i3-530 (CPU) and GeForce 9600 GT (GPU) with 2 GB RAM and 16 GB storage. For the recommended experience, you need a Core i5-3330 and GeForce GTX 560 with 4 GB RAM. Your Xeon E5-2699 v4 and GeForce RTX 5090 both exceed the recommended specs, so you're well-positioned for a great experience.
These League of Legends 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.
