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 ultra, the GeForce RTX 4090 sets the ceiling at about 398 FPS, while the Core Ultra 7 265 has headroom up to 450 FPS. In this scenario, the GPU limits the CPU potential by 12% (FPS gap: 52 FPS). Overall distribution: GPU limits 10/12 cells, CPU limits 0/12, balanced 2/12.
The Core Ultra 7 265 and GeForce RTX 4090 stay close in effective frame-generation ceiling across most presets, so neither side consistently suppresses the other by a large margin.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | Balanced | GPU Limits CPU 6% | GPU Limits CPU 8% | GPU Limits CPU 12% |
| 1440p (2K QHD) | Balanced | GPU Limits CPU 8% | GPU Limits CPU 9% | GPU Limits CPU 11% |
| 4K (Ultra HD) | GPU Limits CPU 7% | GPU Limits CPU 10% | GPU Limits CPU 10% | GPU Limits CPU 7% |
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 Core Ultra 7 265 + GeForce RTX 4090 pairing runs this title with CPU utilization between 5% and 27% and GPU utilization between 7% and 58%. Core Ultra 7 265 keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 16% at 1080p to 54% at 4K, while CPU averages move from 17% to 14%.
Neither component is close to saturation: CPU tops out at 27% and GPU at 58%. This pattern suggests possible engine-side limits, an FPS cap, or workload constraints unrelated to raw hardware throughput.
At 1080p, averages sit around CPU 17% and GPU 16%. At 1440p, that shifts to CPU 16% and GPU 29%, and at 4K it reaches CPU 14% and GPU 54%. 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 14% (9-20%) and GPU 56% (53-58%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core Ultra 7 265 remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core Ultra 7 265 and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the Core Ultra 7 265 paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 250 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 675% above the recommended requirements.
This CPU + GPU combo costs approximately $1969 ($320 CPU (Rank #54 Value) + $1649 GPU (Rank #77 Value)). Your GeForce RTX 4090 provides phenomenal top-tier performance but at a premium enthusiast price. Since you are essentially at the ceiling of current hardware capabilities, there are no meaningful performance upgrades available. However, if you wanted a more cost-effective build that still delivers a great experience, you could theoretically step down to a high-end card with a significantly better value rating.
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: 1080p medium, 1080p high, 1080p ultra, 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 Core Ultra 7 265 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.
