I have WPF application that performs scrolling of three xaml controls in circular manner.

If I use simple control without much styles or instead use a simple image in the element, then scrolling goes fine and application performance is good.

However, if I load the control with heavy WPF styles,then at very high resolution say (1400 * 900) systems, scrolling gets jerky and CPU usage increases.The problem exists with machines with low graphic card.

I studied this and found that WPF can take advantage of hardware rendering pipeline but couldn't find any working example.

Is there some way in WPF by which we can use heavy styled xaml controls with good performance on  PCs with UMA graphic card?

WPF has always been targeted at hardware-assisted vector graphics cards.  It’s no surprise to me that heavily-styled graphics are slow on low-end graphics cards where much of the rendering has to be done in software.

This is somewhat off-topic for this forum.  I suggest you try one of the Microsoft WPF forums, such as:

Thanks for the reply.

I have already lowered the Bitmap effect and applied the caching still in need more performance, can you suggest something ?

Can i somehow further reduce the rendering quality while doing doing some particular task?

Thanks
