Use too much GPU

Answer 1 · 2023-04-15T23:40:17.000Z

@Eavilaswayce it's the carrousel who use a decent amount of the gpu like literraly the red loading bar

How do you know this? The red loading bar is just a DoubleAnimation which there are like 100 of in the launcher so I don't see why this one would be any different :/

I did, however, read somewhere that the use of DropShadow effects in WPF increases GPU usage a lot for some reason, this could be it possibly.

Well open your task manager and look how much gpu is used, 30+% when the carrousel is running and 0 when i put the mouse on it ( so it stop ).

Damn you're right, for me it uses ~18% GPU and then when the carousel stops it's 0%. Wonder if it's possible to limit GPU usage on a WPF app?

No idea but for real the refresh rate of your animation is probably too fast even to see

Maybe we could just remove that animation ? @Eavilaswayce Yeah it looks cool but for what it cost 😅

I just took a look @Eavilaswayce. The problem is that the animation is rendered for every px between 0 and the width of the rectangle. If there was a way to make the animation render only every 5 pixels, it would improve performance and no one would notice a difference.

you can test it by changing the time the animation take with more time the animation have less px to travel per sec and so consume less gpu
