Editor and FPS

Developer Talk
#1

Urho3D editor show in FRAPS ~250 fps stable

Blender3D editor show ~0-5 fps if i do nothing
and when i quick rotate scene or move 3d object
fps is up to 60 fps (may be limit in blender)

In Godot engine editor FPS also how in Blender.
Only limit ~20 fps.

Question:
When i work in Urho3D editor my hardware do big work (always)
It may be necessary to revise the method of updating in editor?

There is a branch for lazy render by hd_:

github.com/hdunderscore/Urho3D/tree/lazy-render

However the UI code becomes a bit dirty, as it’s checking for any changes and forcing a render in that case.

#3

Okey.
I think, this is target of branch:
“Initial lazy rendering for GUI applications – attempt to only render?
? when the UI is updated, or when otherwise told by a call to Renderer::SetRenderFrame.”

#4

It is also possible to do this by using Render-To-Texture. Scorvi’s C++ Editor does this, and by extension my branch also does this (though not by default, the option is there). It should be possible to implement in Angelscript as well.

#5

I’ve just added “engine.maxFps = 60;” into editor.as , sure, not as efficent as blender’s 0-5, but at least my GPU fan won’t buzz like it is about to takeoff.

#6

I got the same effect as a FPS in Blender.
When I tested the one game engine,
if the application window is not in focus - all the contents of the window
is updated only when cursor is moved over.
When the cursor does not move anything not updated (including animation, particle effects, etc.)
FPS - from 0 to the limit.
