How can I fix this issue where my plane starts jittering when going fast. it only happens on low fps less than 60fps and the lower the worst it gets. I have the plane go forwards using an add force node but it still happens even when applying zero force.
Your frame rate is probably too low for the physics to evaluate properly. One of the ways to elevate the situation is to turn on physics sub stepping
This will make the physics calculations update faster then the frame rate of the game.
You may need to fiddle around with the parameters to get good results.
If you have any physics calculations on tick your could try moving them to Event Async Physics Tick. It’s a new variant of tick specifically for physics calculations.
You can also try turning on async physics (not sure if it’s on by default in newer versions of the engine).
Already tried it and it didn’t really work. it started happening after I updated my project from 5.1 to 5.4. Maybe I didn’t set the values right, Can you recommend what values I should set for substepping? also I would rather the fix is within the blueprint it self.
