Hardware overlays and GL compatibility.....

Hi gurus,

I’ve been given the task at work of writing a 3D visualization control (real-time) for which I would like to use GL. The software it will integrate with uses a hardware overlay to display real-time camera images. I was wondering if there may be some intrinsic problem with having a GL context and hardware overlay in-process together, or whether the driver for DDraw and GL will live happily together.

I guess I’m thinking about NVIDIA and ATI cards, the oldies as well as the newies (such as the Rage 128 etc.).

Any experience of this gurus?
