Starfield currently has a maximum frame rate of 30fps on consoles, and there is no "performance mode" available to enhance the frame rate by sacrificing graphical fidelity. However, Digital Foundry decided to investigate whether it would be possible to run a performance mode on the Xbox Series X. To do this, they built a custom console using the AMD 4800S Desktop Kit and replaced the GPU with the RX 6700. While the PC setup does not perfectly match the specifications of the Series X or the PS5, it does replicate some of the architectural features of the Xbox's CPU and provides similar processing power as the current generation of consoles. The final step was to fine-tune the graphical settings to match those of the Series X.
Running Starfield at 4K resolution with FSR 2 enabled (but no dynamic resolution scaling) occasionally exhibited 60fps, predominantly in confined game environments. However, during space travel, the frame rate ranged from 35 to 50fps, and the majority of the game maintained a frame rate of 30 to 40fps. To assess performance, DF then reduced the resolution to 1440p, akin to the Xbox Series S. At this resolution, Starfield achieved a minimum of 40fps, with a significant portion of the game rendering at a smooth 60fps. DF suggests that Bethesda may consider introducing a 40fps mode for 120Hz displays, and Variable Rate Refresh screens might also benefit from this addition.
Although the console version is currently locked at 30fps, the frame rate remains consistent. It is worth noting that despite Starfield's performance, the game has gained immense popularity. In fact, the sci-fi epic recently set a new record for concurrent players on Steam.
