DoubleCAD XT v5 has released
The closest that IMSI has at this time is in TurboCAD Pro. Not only does it have photorealistic rendering, but also artistic render styles that include hand drawn effects, water colors, etc. See a few simple examples here: http://www.turbocad.com/TurboCAD/TurboCADWindows/TurboCADPro17/Rendering/ArtisticRendering/tabid/1552/Default.aspx
