Bethesda's Creation Engine 2 is CPU-dependent, especially in cities, and requires an SSD for asset streaming. Optimization tends to favor AMD slightly, but generally requires powerful hardware to run smoothly.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, performance runs at around 27 FPS. At 1440p, performance is around 27 FPS. At 4K, performance is around 27 FPS.
The GeForce RTX 4090 is 52% above the recommended GPU (GeForce RTX 2080) for Starfield. The Pentium 2127U is 92% below minimum CPU requirement.
The Pentium 2127U 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 Pentium 2127U sets the ceiling at about 27 FPS, while the GeForce RTX 4090 could reach 146 FPS. In this scenario, the CPU limits the GPU potential by 82% (FPS gap: 119 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Pentium 2127U 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 82% | CPU Limits GPU 79% | CPU Limits GPU 75% | CPU Limits GPU 71% |
| 1440p (2K QHD) | CPU Limits GPU 79% | CPU Limits GPU 76% | CPU Limits GPU 72% | CPU Limits GPU 67% |
| 4K (Ultra HD) | CPU Limits GPU 68% | CPU Limits GPU 65% | CPU Limits GPU 60% | CPU Limits GPU 52% |
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.

The Pentium 2127U + GeForce RTX 4090 pairing runs this title with CPU utilization between 98% and 100% and GPU utilization between 6% and 37%. Pentium 2127U reaches high load in heavier scenarios, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 18% at 1080p to 26% at 4K, while CPU averages move from 100% to 99%.
From a utilization perspective, this is a CPU-heavy load profile. At 1080p (Full HD) Low, the Pentium 2127U reaches 100% average load (99-100%), while the GeForce RTX 4090 remains comparatively lower at 14% (6-22%). This points to heavier CPU-side frame preparation work, but utilization alone does not define the FPS limiter.
At 1080p, averages sit around CPU 100% and GPU 18%. At 1440p, that shifts to CPU 100% and GPU 22%, and at 4K it reaches CPU 99% and GPU 26%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
4K (Ultra HD) Ultra is the most balanced preset based on this dataset. It runs around CPU 98% (98-99%) and GPU 28% (20-37%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Pentium 2127U remains stable for consistent frame delivery.
Upgrade priority should be the CPU. The Pentium 2127U reaches 100% average load at 1080p (Full HD) Low while the GeForce RTX 4090 remains comparatively underutilized, so a faster processor would improve frame-time consistency and top-end FPS.
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.

The Pentium 2127U and GeForce RTX 4090 will struggle to run Starfield at smooth framerates. At 1080p Ultra, you can expect around 27 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.
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 Starfield, upgrading the CPU would have the biggest impact on performance. The Pentium 2127U 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.
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.
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.
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.
