Hi guys, I am going to make my own simple DirectX game. I am using DirectX 9.0c is because Direct3D 9.0 has the wider audience base than OpenGL 2.0 though I am more familiar with OpenGL. I hope this will not degrade into a D3D versus OpenGL topic because I have made up my mind on Direct3D 9.0c. I got a question to ask because I heard a rumour that if I use the latest DirectX 9.0c SDK, not DirectX 10 SDK, my DX application cannot be run on users' PC even though the users already has DirectX 9.0c if it is an 'older' DirectX 9.0c. Is this rumour true? If it is true, then which older DirectX SDK should I download? Or should I use C# and XNA? Thanks for your replies! And TGIF, have a nice weekend!

I want to prevent any need for user to install any prerequisite software to run my software and to make my downloads smaller without having the DX redistributives.

Newer versions of DX9.0c have a different d3dx dll for each release (every 2nd month). Users will need the appropriate DLL, which you cannot ship by itself (against the D3D license agreement).

You can:

1. Attempt to strip down the redistributable package to be as small as possible.

2. Provide a link to the D3D web installer. This will check which DLLs they have, and download everything they don't have (whether they need it or not).
