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

At 1080p low, the Athlon 240GE sets the ceiling at about 114 FPS, while the GeForce RTX 4090 could reach 661 FPS. In this scenario, the CPU limits the GPU potential by 83% (FPS gap: 547 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Athlon 240GE 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 83% | CPU Limits GPU 79% | CPU Limits GPU 74% | CPU Limits GPU 70% |
| 1440p (2K QHD) | CPU Limits GPU 77% | CPU Limits GPU 72% | CPU Limits GPU 66% | CPU Limits GPU 59% |
| 4K (Ultra HD) | CPU Limits GPU 67% | CPU Limits GPU 64% | CPU Limits GPU 55% | CPU Limits GPU 49% |
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.

The Athlon 240GE + GeForce RTX 4090 pairing runs this title with CPU utilization between 44% and 88% and GPU utilization between 42% and 78%. Athlon 240GE stays in a controlled operating range, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 44% at 1080p to 74% at 4K, while CPU averages move from 66% to 66%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 76% average at its highest-load preset, while the Athlon 240GE peaks at 68% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 66% and GPU 44%. At 1440p, that shifts to CPU 66% and GPU 52%, and at 4K it reaches CPU 66% and GPU 74%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) Ultra is the most balanced preset based on this dataset. It runs around CPU 64% (46-83%) and GPU 76% (74-78%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Athlon 240GE remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Athlon 240GE and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the Athlon 240GE paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 103 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 29% below the recommended requirements.
This CPU + GPU combo costs approximately $1759 ($110 CPU (Rank #370 Value) + $1649 GPU (Rank #77 Value)). 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 League of Legends, upgrading the CPU would have the biggest impact on performance. The Athlon 240GE 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.
