IDirect3DQuery9::GetData() fails to return S_OK on multi-core CPUs
Tue, 22 Apr 2008 01:01:00 -0700
I'm using the following code to wait for my scene to be fully rendered before
using IDirect3DSwapChain9::Present() to display it on the screen. This

Thu, 17 Apr 2008 09:51:24 +0200
I have made several very small applications (<100KB) that use DirectX 9. I
usually distribute them to people via email in a zip file, where the

ID3DXFont::DrawText Italic Problem
Sun, 13 Apr 2008 07:23:01 -0700

I've noticed using C#, managed DirectX and Direct3D.Font does have this
problem (I hope this indicates a solution or workaround is possible).
Thank for you help.
Phil. ...
