Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

6 stutters (25 slow frames) · 1.6 s lost

Main cause: Game computation (25 occurrences). The worst stretch cost 646 ms of lost frames. 88% happened in the first ten minutes: the signature of shader compilation, which will not happen again on this game.

Balanced

Neither one dominates (55% of the frames limited by the card, 45% by the processor).
