Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

183 stutters (283 slow frames including 20 freezes) · 15.7 s lost

Main cause: Game computation (268 occurrences). The worst stretch cost 3.5 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.
