God morning!
I was wondering if any of you know if it will be a change of speed if triangles are drawn with another winding. OpenGL and DirectX are as you know using different windings while drawing tris and I'm about to make my DirectX engine have two rendering pipelines, one for DirectX and one for OpenGL. I was thinking that if I just change the winding for OpenGL I could use the same data.
Take care!

Almost certainly, there will be no performance detriment to changing the winding order. The vast majority, if not all, OpenGL implementations will not care, performance-wise, about the winding order.
