Hi All, First of all I would like to say - NeHe - Thank you! Thanks to this site I've learned how to write my own (now very simple) 3D apps :-) As you can see I'm newbie in 3D Programming but I would like to learn Cg programming. Now writing some small programs is not a problem for me. Because I'm using Mobile Radeon 9700 which can have some problems with some newer profiles, I would like to know how to actually used version. How can I convert CGprofile variable to string ? Or maybe there is some other solution ? I will be very grateful if you could tell me how to display some information on top of OpenGL window (i.e. FPS counter). TIA for all your help. Best wishes, Rob
