Key takeaways

Bad session

Stutters cost a noticeable share of the playtime.

6 stutters (20 slow frames including 10 freezes) · 13.4 s lost

Main cause: Game computation (8 occurrences). The worst stretch cost 12.9 s of lost frames.

Pace set by the processor

The processor set the pace on 73% of the frames: it decides how many frames per second you get, not the graphics card.
