Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

12 stutters (26 slow frames including 6 freezes) · 1.9 s lost

Main cause: Graphics load (15 occurrences). The worst stretch cost 985 ms 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 92% of the frames: the usual situation for an uncapped game.
