WPF 3D性能问题是由于显卡内存不足所致？

Question

My project uses 3D flip animations to show the forms. My problem is that the transitions are very slow in an XP machine. I checked the graphics card memory and its only 64MB. Does upgrading the graphics card make any difference in the perfomance?

Answer 1

It may make some difference, but there are other alternatives to manage UI performance if your app is intended for wider distribution.

Often, software rendering will outperform hardware on lower-end machines. This can be enabled (for ALL WPF apps) using a registry setting detailed here .

Additionally, WPF exposes a property that broadly categorises a machine's performance into three "tiers." Information on those can be found here . You can expose this value as a property (say, on your App object) and use it in a Xaml trigger to selectively disable animations or high-end effects (shadows/blurs/etc) that might cause issues on slower machines.

On XP you may find that both of these are of benefit.

Answer 2

It is not just upgrading the graphics card that could benefit your application.

WPF doesn't run optimal on Windows XP .

Answer 3

You need to check several things: For rendering Tier 2 DirectX version: must be greater than or equal to 9.0. Video RAM: must be greater than or equal to 120MB. Pixel shader : version level must greater than or equal to 2.0. You should take look on Graphics Rendering Tiers http://msdn.microsoft.com/en-us/library/ms742196.aspx
