   Texturefilter in Samplerstate
  in my program i need to set the texturefilter in the samplerstate to the point-filter.but when i turn on anisotropic filtering on the graphics-card it overrides the samplerstate.is it possible to turn off this effect without changing the settings of the graphicscard?thank you for your suggestionsPS: my graphicscard: hercules radeon 9500PRO 
  No.  You''ve told your card to ignore the application and use aniso filtering.  Turn off all overrides when developing to ensure you actually do setup every state you need to.
