2D-platformer is hitching at constant 120/60fps

Hello there,

this is not my video but it is the closest to what I'm experiencing with my 2D-platformer project. I'm using blueprints only but as far as I can tell, they are pretty optimized.

In the editor, even though my framerate is constantly at around 120fps but most of the time my tile maps (floor and parallax) lag behind like in the video. (or worse!) When I nativize my blueprints inclusively, the lag in the packaged game is bearable but still present, even though I am only using sprites, no complex meshes.

May this be hardware dependant? Think I’ve read something regarding that before…
I’ve got a AMD R9 280X, are there any issues related to this model?
What role do Overlaps play there? There’s plenty of them in my levels.
Is there a problem with Paper2D tilemaps?

Greetings,
Vinni

Turns out the culprit was UDP messaging all along. No more stuttering after deactivating it…
