I'm an RIA developer and I try to use Flash / Flex / Air whenever possible because it's so much easier to build quality interfaces. I was very excited by the release of WPF and Expression Blend, believing it would bridge the power of .Net with modern GUI and a year and a half ago I tried developing an application in it.

I have seen the opposite, in many of our applications.

WPF seems to scale and perform quite well. We've had very few issues with it, although you do have to watch for different things in terms of performance than you do with Windows Forms, etc.

In addition, the rich databinding support makes business application development very, very nice, especially once you get over the learning curve and handle things in a clean, well designed manner.

Your system is probably fine, in terms of specifications for CPU/RAM/etc (it's better than some of mine, actually), however, I'd guess you may be running into perf. problems due to the graphics solution. The 6150 line supports SM3, so you should be getting hardware acceleration in your UIs in WPF, but the performance is not great. This isn't completely unexpected, since the graphics chipset is a 4+ year old chipset using embedded graphics.

I'd bet that if you stuck a new (even very cheap) graphics card in your box, you'd have a very different view of WPF performance.

Thanks. I suspected that might be part of the issue...

Hello rblinzler,

In addition to Reed's,

From the http://msdn.microsoft.com/en-us/library/ms742196.aspx

NVidia GeForce 6150 supports the render-tier 2.

The NVidia 6XXXislaunched from 2004.

If there is any new driver for it,you can try to upgrade the driverto see if it works.

Thank.
