Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

87 stutters (145 slow frames including 15 freezes) · 13.2 s lost

Main cause: Game computation (140 occurrences). The worst stretch cost 4.5 s of lost frames.

Pace set by the processor

The processor set the pace on 99% of the frames: it decides how many frames per second you get, not the graphics card.
