Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

178 stutters (255 slow frames including 17 freezes) · 16.8 s lost

Main cause: Game computation (250 occurrences). The worst stretch cost 4.5 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.
