Hi Mikhail,
Why is my rendering of my world so slow?
Also, when I select to render in
DirectX, it turns back to Software
rendering. Yet when I choose OpenGL, it
renders very slowly. I am using Windows
2003 Server with DirectX 9 installed,
and when I open DXDIAG it says that
DirectDraw, Direct3D, and AGP Texture
Acceleration are not available. Is this
due to my using 2003 Server or is this a
problem with DirectX?
I hope you understand my problem, and
thanks for the help so far.
Kelly
