Directx10: MSAA max texture size?

In DirectX 10, how do I find out the maximum texture size for a MSAA texture for a given sample count/quality?

I'm trying to render some geometry using Direct2D rendering to a Direct3D MSAA surface but for large textures (~5000x2500) I get strange results. Everything gets rendered fine if the MSAA sample count is reduced from 8 to 4. I don't get any errors when creating the textu开发者_如何学Gores or when rendering.

Thanks!

You can use ID3D10Device::CheckMultisampleQualityLevels to check for support.

You can also use the CAPS viewer tool that installs with the SDK.
