Jerky camera movement in standalone and packaged builds

Hi,

I have created a scene where a camera moves at a steady rate. It is perfectly smooth in PIE, however in standalone or packaged builds a jerkiness appears, despite a steady 62fps.


The problem is easy to replicate:

  1. Create a new project.
  2. Create a new map and select Default. Scale the X and Y value of the floor to 20. Save the map.
  3. Create a pawn blueprint.
  4. Add a Camera Component and set its Z location to 500, and its Y rotation to -90.
  5. Add a Floating Pawn Movement Component and set its max speed to 500.
  6. In the event graph, off the Event Tick, call Add Input Vector on your Floating Pawn Movement component. Set the X value of World Vector to 1.
  7. Place the pawn at 0,0,0 in your map. In its details panel set Auto Possess Player to Player 0.
  8. Play the game in editor and notice a smooth birds-eye scrolling effect.
  9. Play the game in standalone and notice it jitter.

The jitter is a lot more noticeable with artwork in the level. I have also tried the camera movement with other methods (manually setting camera location accounting for delta time, and using a level sequence to animate the location) but I get the same results.

How can I achieve smooth camera movement?
