Cloud animation not smooth at higher campaign time

[Draradech]

KSP2 0.1.0.0.20892   -   Windows 10 Home 21H2   -   Ryzen 9 3950X   -   RTX 2080 Ti (Driver 528.49)

Observed / Repro Steps:

1) Start new campaign
2) Observe smooth cloud movement
3) Time-warp ~2y to the future
4) Observe clouds moving in steps (~1s per step)

This can be done completely in the KSC scene, but flight scene is affected as well. I noticed in flight after I returned from Duna, which obviously needed time-warp.

Expected:

Smooth cloud animation independent of campaign time.
