As I see, NeHe in his lessons use ChoosePixelFormat and SetPixelFormat. I add little change and I`m use ChoosePixelFormat, DescribePixelFormat and SetPixelFormat. On my unaccelerated videocard and on TNT all work fine (I try MS ICD and SGI ICD drivers), but on TNT2 and Voodoo3 creation of rendering context failed. Maybe, I must remove DescribePixelFormat call? Thanx

Dunno, sounds like you should. Possibly those cards don''t support it?

Nope, TNT and Voodoo 3 support OpenGL and NeHe tutorials work fine on this cards
