Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

301 stutters (518 slow frames including 41 freezes) · 27.2 s lost

Main cause: Game computation. The worst stretch cost 3.0 s of lost frames.

Pace set by the processor

The processor set the pace on 100% of the frames: it decides how many frames per second you get, not the graphics card.
