Key takeaways

Bad session

Stutters cost a noticeable share of the playtime.

26 stutters (186 slow frames including 87 freezes) · 71.9 s lost

Main cause: Game computation (162 occurrences). The worst stretch cost 20.6 s of lost frames.

Pace set by the processor

The processor set the pace on 92% of the frames: it decides how many frames per second you get, not the graphics card.
