Camera stuttering

[MoczusYT]

Hi everyone,
I’ve run into a strange issue with the camera in my project. When the camera follows the player, it looks like it is “jumping” from pixel to pixel instead of moving smoothly. The player’s movement itself is fine – the problem is only with the camera.

Here’s what I’ve noticed:

• The effect looks like the camera is locked to whole pixels (pixel-perfect), so it never moves in sub-pixel increments.
• I tested this on different GPUs (RX 570 and Intel ARC B570) and the result is exactly the same, so it’s not hardware-related.
• I tried adjusting the camera settings (catch-up speed, forecast time, maximum speed, etc.), but the stuttering/skipping effect is still there.
• It feels like the camera doesn’t interpolate between frames, which makes the movement look choppy.

Is there a way in GDevelop to make the camera move smoothly (with sub-pixel precision) instead of snapping to whole pixels?
Or maybe there’s a known workaround to keep sprites pixel-perfect but allow the camera itself to move fluidly?

Any advice or examples would be greatly appreciated!
(I really want to improve this camera jumping because I’m planning to release this game on Steam, and it looks very unnatural. It’s like 20fps.)

I’ve posted the same problem here a while ago.

FIX camera micro stuttering

Hey there… In my game i’m using a metroidavania similar camera. Basically i created a placeholder object that act as camera focus… when the player enter a room this object is binded to the player position. when the player start to move (eg. to right) this object move first at + 100 px position…and stay at this distance (binded to player) to get a farest view of the room these events [Cattura] works fine… and i tested and works with tweens too. The problem is that the lerp (and tweens)…

it’s not a spec problem.

I think the issue is that the camera relies on the player’s position readings before the movement occurs.
what we want is the camera synched with player position…in some way…like the camera know where the player is without reaing its coordinates…science fiction

i tried everything without success…so let me know

No, but in my case it could also be because I have over 2,000 objects on the map. It’s not necessarily the camera. I’ll check it with the rest in a moment, but it will take a while to remove them down to 1,000.

LOL…ok then it could b that.
