Normally yes -- a bit similar to e.g. when a game is displaying a seemingly 'static' image (when you don't move your character), then the GPU is still rendering

- amelius 9y agoYikes, that would indeed be the first thing to fix on a battery-powered platform then.
- captainmuon 9y agoWhat?! That sounds like something I would write as an amateur. I thought that modern graphics systems would be smart enough to only render when the screen has actually changed. I.e. a tick still comes at 1/60 times a second, and it checks if a region is dirty, but the whole copying of textures and re-compositing (which practically doesn't take time - or rather fixed time - and runs on the GPU, but costs power) is only invoked when something is dirty. Actually, I remember reading something that Windows doesn't do any blitting / buffer swapping if you just leave it idle and no updates happen on screen. However, there are many ways to throw this off and force drawing every frame if you are not careful.
