Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

50 stutters (304 slow frames including 185 freezes) · 48.1 s lost

Main cause: Game computation. The worst stretch cost 6.3 s of lost frames.

Pace set by the processor

The processor set the pace on 70% of the frames: it decides how many frames per second you get, not the graphics card.
