Hi,

Open GL is part of the Video card drivers.

Check "my computer" details to see which display type you have.

If it's an on-board (built-in) display chipset, you'll need to update from the Motherboard manufacturer. If it's an add-in card, then visit the card manufacturer.

nVidia created the Open GL instruction set, ATI prefer Direct X - that doesn't mean that they won't run the other, but hints at a preference for Trainz...

OpenGL was created by Silicon Graphics a UNIX work station company. It was never designed for Windows and Game playing. OpenGL 3 is now available but still contains a lot of old commands to maintain compatibility with the old UNIX graphic environment. It is an open standard but allows manufacturers to add proprietary extensions onto it which nVidia have done.

Microsoft designed DirectX to be manufacturer neutral and be optimised for games and the Windows environment.

So if I have a Nividia Video Card...Open GL is the best setting ?
Or does Direct X provide better quality, and is recommended for Trainz ?

nVidia have a technical assistance program to help game companies get the most out of their cards. Auran take advantage of this. nVidia provide input to Microsoft on the DirectX standard.

Each card model will be slightly different on how OpenGL and DirectX is implemented and also how good the drivers are.

So you've back to the empirical method sometimes known as suck it and see. Try them both and see which you are happier with.

With my NVidea GT220 (See below) DirectX has a better frame rate than Open GL but water looks a bit wierd.
Try it both ways and see. First be sure your video driver is up to date.
