To work around this, disabling Interpolation and setting Fixed Fps to 0 (or a very high value such as 1000) seems to do the trick.

This works in beta 10. I can confirm it's still not working beta 10, my refresh rate is 165 and it's jerky (30fps looking) if interpolation is on.
I have stumbled upon this issue recently. The workaround looks quite trivial, so it'd be nice to fix this soon instead of having to do apply it for every particle node...

There's a PR changing the default, but reduz would prefer we fix interpolation (which is nontrivial): https://github.com/godotengine/godot/pull/70777
Oh, but in my project I temporarily disable interpolation when the GPUParticles node is paused (by checking for NOTIFICATION_PAUSED/UNPAUSED), and that's all. Setting the fixed FPS to 0 doesn't seem to matter to me. Perhaps something has changed after a year?
I feel like the engine should just internally disable the interpolation if the particles are paused. They're not gonna move anyways, right?
Disabling interpolation on pause would, in theory, make the particles instantly snap to their actual position, which would look jarring. Therefore the solution may not be as straightforward as assumed.
Not seeing any jarring jump. It's certainly better than epilepsy introducing jittering ;) For anyone stumbling on this, here's a quick script you can attach to your particles (make sure the 2D/3D matches) to fix the jittering for now:
extends GPUParticles2D
func _notification(what):
match what:
NOTIFICATION_PAUSED:
interpolate = false
NOTIFICATION_UNPAUSED:
interpolate = true

With high-speed particles the issue is the most evident.
Steps to reproduce
Create a GPUParticles2D and add a process material, make the particles high-speed, increase project FPS (possibly by turning VSync off) and pause the game.
Some observations:
Minimal reproduction project
Didn't have time to make one, but I'll get to it later if it'd help.
