Open GL vs Direct X

Does anyone know how to use OpenGL to draw instead of DirectX in Blitz Plus or is it just another graphics driver that needs to be checked and set with GfxDriverName$ and SetGfxDriver? This would mean showing the user a list of their drivers before the game started I assume, unless Open GL has *exactly* the same working on different PCs, then I could try to set it by looping through the list of graphics drivers and picking it if it exists, I might even be able to just search for "Open GL" as a substring. Does anyone know if OpenGL handles vertical refresh differently fromDirectX?

Blitz Plus doesn't support OpenGL out of the box, although people have produced libraries to add OGL support - but it would mean changing your code a bit. No idea with regards to the refresh.

OK thanks anyway. It does say on the products page that it supports OpenGL and I once saw a thread about changing the driver to it I'm sure.

Wow that's news to me - sorry if I misinformed you.

Like you said, it's just another graphicsdriver you can change to.

OK, thanks, any idea if the name is the same on all systems?
