Key takeaways

Bad session

Stutters cost a noticeable share of the playtime.

833 stutters (7952 slow frames including 570 freezes) · 503.4 s lost

Main cause: Game computation. The worst stretch cost 27.0 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.
