I had to borrow some of the the opengl example from sfml and use it in the code, as it would of taken way too long to get the original code together, but the result/error is still the same.

contextSettings.depthBits = 48;

I have the latest Nvidia drivers, I don't think that's the problem. I'm also using SFML 2.2 if that helps.

I'm pretty sure I have clasped the concept now, cheers.
