Key takeaways

Bad session

Stutters cost a noticeable share of the playtime.

18 stutters (21 slow frames including 5 freezes) · 20.6 s lost

Main cause: Game computation (20 occurrences). The worst stretch cost 19.0 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.
