Performance Summary
The Core i5-2405S + GeForce RTX 4090 pairing runs this title with CPU utilization between 92% and 100% and GPU utilization between 27% and 97%. Core i5-2405S reaches high load in heavier scenarios, while GeForce RTX 4090 carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 48% at 1080p to 87% at 4K, while CPU averages move from 98% to 96%.
Load Interpretation
From a utilization perspective, this is a CPU-heavy load profile. At 1440p (2K QHD) Low, the Core i5-2405S reaches 100% average load (99-100%), while the GeForce RTX 4090 remains comparatively lower at 48% (37-59%). This points to heavier CPU-side frame preparation work, but utilization alone does not define the FPS limiter.
Resolution Scaling
At 1080p, averages sit around CPU 98% and GPU 48%. At 1440p, that shifts to CPU 99% and GPU 55%, and at 4K it reaches CPU 96% and GPU 87%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
Optimal Settings Recommendation
4K (Ultra HD) High is the most balanced preset based on this dataset. It runs around CPU 95% (92-98%) and GPU 86% (83-90%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i5-2405S remains stable for consistent frame delivery.
Upgrade Insight
Current utilization does not show an urgent upgrade requirement for either component; the Core i5-2405S and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.
- High GPU Load: You typically want to see High GPU Utilization (90%+) and moderate CPU usage when visual settings are heavy. This indicates the graphics pipeline is under strong load, but the exact FPS limiter should still be confirmed by the FPS ceiling analysis.
- High CPU Load: If you see High CPU Utilization (85%+) paired with lower GPU utilization, the processor is handling a disproportionate share of frame preparation and game logic. That can point to CPU-side pressure, but it should not be treated as a direct replacement for FPS ceiling analysis.
- Low CPU and GPU Load: If both CPU and GPU utilization are relatively low, it means the hardware is waiting on something else. This could be a game engine limitation, poorly optimized code, or an artificial framerate cap like VSync holding performance back. It does not mean both parts are equally fast in FPS terms.

Frequently Asked Questions
2Is there a more cost-effective setup to run Starfield?
This CPU + GPU combo costs approximately $1769 ($120 CPU + $1649 GPU (Rank #77 Value)). This is a well-balanced setup, meaning you're getting good value from both components without significant waste.
3Which component should I upgrade first to improve Starfield performance?
This setup is already well-balanced for Starfield. No significant bottleneck - CPU and GPU are well matched across all settings. Both the Core i5-2405S and GeForce RTX 4090 complement each other effectively, so upgrading either component individually would yield diminishing returns. If you want more FPS, you'd benefit most from upgrading both CPU and GPU together.
4Does this setup support Frame Generation for Starfield?
Starfield 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.
5What are the minimum and recommended specs for Starfield?
Starfield requires at minimum a Core i7-6800K (CPU) and GeForce GTX 1070 Ti (GPU) with 16 GB RAM and 125 GB (SSD Obrigatório) storage. For the recommended experience, you need a Core i5-10600K and GeForce RTX 2080 with 16 GB RAM. Your hardware falls below the minimum requirements for this game, which may result in poor performance.
6How accurate are these Starfield FPS estimates for the Core i5-2405S and GeForce RTX 4090?
These Starfield 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.
