Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

59 stutters (103 slow frames including 22 freezes) · 14.0 s lost

Main cause: Game computation (90 occurrences). The worst stretch cost 5.0 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.
