A AMD RX 7800 XT paired with a Intel Core i5-12400F lands around 74 fps in Starfield at 1080p with High textures, Medium shadows and FSR Performance. Ray tracing is left off on this pairing. These values come from the same model the interactive optimizer uses, applied to this exact hardware pair rather than a generic preset.
Based on benchmark data and community reports for this hardware combination — treat as an estimate, not a guarantee. How we calculate this.
Your CPU is limiting FPS here
Intel Core i5-12400F is holding back your AMD RX 7800 XT at 1080p in Starfield. A faster CPU could get you closer to ~89 fps at these settings.
Estimate only — based on a 20% uplift for a moderate CPU bottleneck, not a measured benchmark.

Starfield's engine spends its budget in places that are easy to miss. Space and small outposts are light; New Atlantis, with its crowd simulation and layered interiors, is heavy and CPU-bound. Any preset that has only been tested on a barren moon is essentially untested.
The other quirk is upscaling. The game's internal resolution scaling has a large impact on both performance and image quality, and setting it correctly is usually worth more than several individual quality sliders combined.
Covers the current Creation Engine 2 PC build with upscaling available. Major cities are the CPU reference; space is not representative.
