Godot 3 vs Godot 4 drawcalls

boruok

Is Godot 3 performs better for UI drawing? Noticing drawcall difference between 4 and 3 branch.
Godot 4, 6 buttons = 6 drawcalls
Godot 3, 6 buttons = 1 drawcall

You can try it by youself:

Make empty scene with Node as root.
Add 6 default buttons to scene.
Run scene.
4 Check monitor (2D drawcall)

Same for Label, Panel, CheckButton, ColorRect, ...

boruok This will happen only if drawn things are exactly the same. But sure there are likely many draw optimizations implemented in v4.

musikai not related to this.

Bothering with drawing optimization is only worth the effort if the frame rate on minimal target hardware drops below 60. In any case, you'd need a more elaborate test than drawing several buttons. GPU performance and consequently engine's internal optimization strategies are highly non-linear and unpredictable. Always benchmark real situations. Making conclusion based on drawing 10 sprites will always be misleading and pretty much pointless.

xyz There is definitely issue where Godot 4 not performs as well as Godot 3.
