Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

98 stutters (164 slow frames including 17 freezes) · 8.7 s lost

Main cause: Game computation (159 occurrences). The worst stretch cost 2.4 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.
