Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

13 stutters (26 slow frames including 11 freezes) · 2.9 s lost

Main cause: Game computation (26 occurrences). The worst stretch cost 709 ms of lost frames. 96% happened in the first ten minutes: the signature of shader compilation, which will not happen again on this game.

Balanced

Neither one dominates (44% of the frames limited by the card, 56% by the processor).
