While the Gallium performance overlay clearly shows a spike in=
 the game's GPU
render time, I'm fairly certain it doesn't exist in the actual display outp=
ut.
It's not limited to the character inventory, but instead happens anywhere, =
even
in the main menu. But I neither can see the cursor skipping, nor the camera=
 in
game, despite of the graph's spike.
I also noticed that there is no such spike when the framerate is below the
refreshrate.

I also tested if there's something similar to observe in Hitman 2: I reduced
visual fidelity to achieve constant 75fps/Hz with vsync, and it always seem=
s to
be 100% free of stutter, also when resuming to move the mouse after suspend=
ing
it for a few seconds.
