Key takeaways

Bad session

Stutters cost a noticeable share of the playtime.

11 stutters (25 slow frames including 14 freezes) · 55.5 s lost

Main cause: Game computation (18 occurrences). The worst stretch cost 42.2 s of lost frames. 100% happened in the first ten minutes: the signature of shader compilation, which will not happen again on this game.

Pace set by the graphics card

The graphics card set the pace on 82% of the frames: the usual situation for an uncapped game.
