ShaderEffect version supported

Question

I just got a new laptop. DxCapsViewer says my PixelShaderVersion is 3.0. How come RenderCapability.IsPixelShaderVersionSupported(3, 0) returns false? I can run all of the cutting edge DirectX10 demos at high frame rates. I was hoping to exploit the instruction counts available in the 3.0 model. Should I ignore the RenderCapability call or am I screwed?

Hello kkennedy1008.

The IsPixelShaderVersionSupported method returns true if the pixel shader version is supported by the current version of WPF.

More in : http://msdn.microsoft.com/en-us/library/system.windows.media.rendercapability.ispixelshaderversionsupported.aspx

It indicates whether the current version of WPF supports or not. It doesn't show the hardware's support.

Now .NET3.5 SP1 doesn't support version 3.

Thanks.
