Hello
I want to build a desktop application, my issue is that a desktop app, doesn’t have to refresh 60 fps all the time like a game and everything I tested makes the GPU be at 100 % while running, so what I want is the app to only update when you are interacting with it, let’s say when you click a button updates the viewport, when move the viewport redraws but when you let go the update stops.

I know I’ve seen something in SDL I think called Lazy Update or Lay rendering that did this.
Hope is clear what I need

I'm using Kha and Zui

thank you

Sorry but Kha is explicitly not made for doing that. You can probably hack something together like that Lazy Update thing but you'll probably have to do it yourself.

the thing is, I want to use the 3D graphics capabilities of Kha cause my app is related to that

It doesn't use 100% on Linux as a native app. You can adjust the fps under the update. I do all my work under the render function and currently have nothing in the update function.
