However when setting FSAA in a device that doesn't support it (for the given texture format) will raise an exception instead. Call stack:@param fsaa The level of multisampling to use. Ignored if the device does not support it.

I don't see anywhere in Ogre's code a check to see whether FSAA is supported, or an "ignore" flag.
Anywhere knows something about it?
It seems to me the Ogre Exception was added after setShadowTextureConfig docs were written. Most likely setShadowTextureConfig was realying that the failure from d3d9Device->CreateRenderTarget would be ignored, leaving textureResources->pFSAASurface as a null pointer.
The right way to do it is to first check FSAA is supported, if not, drop the setting.
