What is jitter, stutter and input lag?: Jitter and stutter are two different alterations to visible motion of objects on screen that may affect a game, even when running at full speed. These effect...

I'm having issues with stuttering in my android for some reason. I'm not sure but I think it might be something to do with video memory(3.2gb as seen in debugger > monitors)?

Can you test 4.4.beta2 or later? This should be fixed by Swappy integration which is new in 4.4. It can be further controlled using the display/window/frame_pacing/android/swappy_mode project setting.

Note that if you compile Android export templates yourself, you should set up Swappy before compiling so that it can be linked against the Android export template. Otherwise, you will get the same behavior as pre-4.4 (i.e. stuttering due to the lack of a frame pacing solution).

If stuttering persists with Swappy, then the stutter comes from somewhere else. It can be due to excessive memory utilization, the GPU not keeping up with the scene load (try reducing the Scaling 3D Scale project setting to 0.5 or even lower) or a CPU bottleneck. What device model do you have?

I am currently using 4.3 and would prefer to hold off of using any beta builds but I can test it if it helps debugging. I have a Iqoo z9 5g

I'm not sure how to go about setting up swappy integration for compiling android export. Please guide me how to do so. Because I tried by just setting up the swappy mode but it doesn't really seem to change much as you had mentioned

I have very slight stutter with an almost empty scene. It only has a few moving circles drawn with draw_circle and instantiated on mouse click. godot 4.4

Please open an issue with a minimal reproduction project attached after looking at the list of bugs with "stutter".

If you are only seeing this when the mouse is moving, this may be due to godotengine/godot#60646.

Probably also worth noting:

1. Physics interpolation is useful for mitigating jitter
2. Stutter may be caused by shader compilation and has a whole article dedicated to it

While these are documented elsewhere, it would be helpful to link corresponding guides here.
