.NET Forum / Languages / C# / March 2008Slow Animation Performance with Multiple Animations
In WPF (even with considerable improvement in version 3.5), while running multiple animations in a single window, The performance of one animation suffers a lot. for example, i have two image transitions on two independent Canvases on a Grid. 1. is simple, slide transformation running, continously from left to right with multiple images. 2. 3D transitions over multiple images. Even after first run, when the images have beeen cached, when the 3D Transition happens, there are lots of jerks in the first transition. What are the reasons and ways to avoid it, if any. Can you post an example of the problem?

Hi, Sorry for the (very)late reply Here is a link to attached solution, http://www.mediafire.com/?5d1xl0cwzug Note whenever the animation on the upper imageslide show starts, esp, 3D Transition, the animation in the bottom strip shakes. tried using both Animation Subsystem of WPF as well as CompositionTarget.Rendering Also here is the dxdiag report as asked by Bob Powell. http://www.mediafire.com/?bjsixwahm44 Thanks. > Can you post an example of the problem? > [quoted text clipped - 13 lines] > > > > What are the reasons and ways to avoid it, if any. Hmm, Several well known authors cite the fact that the animation system is indeed the most costly of the WPF features. The capabilities of the system will also be likely to change depending on the graphics card capabilities for DX9. As well as posting the example as Nicholas suggests can you post the DXDIAG report too?
