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 375 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 341 FPS. At 4K, all settings exceed 252 FPS.
The GeForce RTX 4090 is 1277% above the recommended GPU (GeForce GTX 560) for League of Legends. The Xeon W-1290P is 249% above the recommended CPU (Core i5-3330).
At lower resolutions (1080p low, 1440p low), the Xeon W-1290P determines the performance ceiling. As graphical load increases at (1440p (medium/high/ultra), all 4k settings), the GeForce RTX 4090 takes over as the primary performance factor. The system is well balanced at 1080p (medium/high/ultra).
At 1080p low, the Xeon W-1290P sets the ceiling at about 559 FPS, while the GeForce RTX 4090 could reach 657 FPS. In this scenario, the CPU limits the GPU potential by 15% (FPS gap: 98 FPS). Overall distribution: CPU limits 2/12 cells, GPU limits 8/12, balanced 2/12.
Your Xeon W-1290P 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 15% | Balanced | GPU Limits CPU 6% | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 7% | GPU Limits CPU 7% | GPU Limits CPU 9% | GPU Limits CPU 9% |
| 4K (Ultra HD) | GPU Limits CPU 9% | GPU Limits CPU 8% | GPU Limits CPU 12% | GPU Limits CPU 13% |
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.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.
See how your processor and graphics card compare against the game official minimum and recommended system specs. The placement of your hardware is calculated using relative synthetic performance scores to help you gauge overall playability.
Your CPU is 249% above and your GPU is 1277% above the recommended specs. Ultra settings at 1080p, or High at 1440p/4K.

Yes, the Xeon W-1290P paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 252 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 249% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
Your GeForce RTX 4090 is already a top-tier graphics card. While it's technically the limiting factor here (which means you are fully utilizing your GPU's visual horsepower exactly as intended), there is no meaningful upgrade path that would drastically improve your League of Legends performance right now. GPU fully utilized at: 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra. CPU-limited at: 1080p low, 1440p low.
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 W-1290P and GeForce RTX 4090 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.
