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 141 FPS. At 1440p, all settings exceed 141 FPS. At 4K, all settings exceed 101 FPS.
The GeForce RTX 4090 is 1277% above the recommended GPU (GeForce GTX 560) for League of Legends. The Ryzen 3 PRO 2300U is 12% below recommended, but 169% above minimum.
The Ryzen 3 PRO 2300U sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GeForce RTX 4090 still has headroom.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the Ryzen 3 PRO 2300U sets the ceiling at about 141 FPS, while the GeForce RTX 4090 could reach 690 FPS. In this scenario, the CPU limits the GPU potential by 80% (FPS gap: 549 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Ryzen 3 PRO 2300U 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 80% | CPU Limits GPU 75% | CPU Limits GPU 70% | CPU Limits GPU 65% |
| 1440p (2K QHD) | CPU Limits GPU 78% | CPU Limits GPU 72% | CPU Limits GPU 66% | CPU Limits GPU 57% |
| 4K (Ultra HD) | CPU Limits GPU 69% | CPU Limits GPU 63% | CPU Limits GPU 61% | CPU Limits GPU 56% |
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.
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 12% below recommended and your GPU is 1277% below recommended, but both meet minimum specs. Playable at Low/Medium settings, 1080p or below.

Yes, the Ryzen 3 PRO 2300U paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 101 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 12% below 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.
For League of Legends, upgrading the CPU would have the biggest impact on performance. The Ryzen 3 PRO 2300U 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, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k 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 setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
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.
