Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

31 stutters (189 slow frames including 66 freezes) · 34.5 s lost

Main cause: Game computation (187 occurrences). The worst stretch cost 8.6 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.
