Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

147 stutters (1104 slow frames including 32 freezes) · 40.0 s lost

Main cause: Game computation. The worst stretch cost 2.0 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.
