Hi,

I am about to develop a kind of a 3D Loader, I am concidering the usage of
managed DX for that, following are some questions I have in mind:
1. Is there any performance differences in compare to the unmanaged version?
2. Does the managed DX is used today for development of NEW 3D related
projects, if so what projects (pointers would be appreciated).
3. The project I am working on include a client side app ( a web control
e.g. ActiveX ) that should run on home users machines, this will require
installation of the .NET Framework on all of client machines, usage of the
..NET Framework will require workstations to download and install the .NET
framework and I am afraid that this may make the product less attractive, I
know that SP2 include the .NET Framework, but what is the percentage of XP
users? what is the percentage of users that will have to download and install
the .NET Framework? Any comment on that would be appreciated...
 
DirectX via C# is ready to go. There is about a 15% performance hit which is
barely noticable on modern hardware. In certain configs and well designed
architectures you can even see a boost over C++.

Here is a stunning example:

As far as deployment you can include the .Net runtime in the client
installer for win2k and xp machines, but you also have to ensure DX9 is
included which can increase the download package to over 200MB!

ok,
aq
