Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

135 stutters (209 slow frames including 24 freezes) · 15.2 s lost

Main cause: Game computation (208 occurrences). The worst stretch cost 1.8 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.
