Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

1049 stutters (1352 slow frames including 119 freezes) · 96.7 s lost

Main cause: Game computation. The worst stretch cost 16.8 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.
