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, frame rates range from 8 to 19 FPS depending on quality settings. At 1440p, frame rates range from 8 to 15 FPS. At 4K, frame rates range from 5 to 9 FPS.
The GeForce RTX 4090 is 52% above the recommended GPU (GeForce RTX 2080) for Starfield. The Phenom II 42 TWKR Black Edition is 75% below minimum CPU requirement.
The GeForce RTX 4090 sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Phenom II 42 TWKR Black Edition still has additional frame-generation headroom.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1440p ultra, the GeForce RTX 4090 sets the ceiling at about 6 FPS, while the Phenom II 42 TWKR Black Edition has headroom up to 86 FPS. In this scenario, the GPU limits the CPU potential by 93% (FPS gap: 80 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Phenom II 42 TWKR Black Edition frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 74% | GPU Limits CPU 80% | GPU Limits CPU 86% | GPU Limits CPU 92% |
| 1440p (2K QHD) | GPU Limits CPU 79% | GPU Limits CPU 84% | GPU Limits CPU 89% | GPU Limits CPU 93% |
| 4K (Ultra HD) | GPU Limits CPU 80% | GPU Limits CPU 84% | GPU Limits CPU 87% | GPU Limits CPU 92% |
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 hardware is below minimum requirements. CPU is the limiting factor (75% below minimum). Expect performance issues. Low settings recommended.

The Phenom II 42 TWKR Black Edition and GeForce RTX 4090 will struggle to run Starfield at smooth framerates. At 1080p Ultra, you can expect around 8 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.
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 Starfield performance right now. GPU fully utilized 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.
