Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

11 stutters (32 slow frames including 20 freezes) · 6.1 s lost

Main cause: Not enough RAM (14 occurrences). The worst stretch cost 3.5 s of lost frames. 97% 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 98% of the frames: the usual situation for an uncapped game.
