Getting Direct3D 10 Samples (April SDK) running

Hi!

I'm using the Vista Beta 2 and I'm trying to run the Direct3D 10 samples in the April SDK. Unfortunately they all don't work on my computer. They should work in a Direct3D 10 software emulation mode, right Do I have to change any (DX) settings Or do I need extra software

Thanks

Which operation system do you use

The Direct3D 10 part of the June SDK works only with Vista Beta 2.

Vista Beta 2, Build 5384, which was made available to public a few days ago.

Is there already a June sdk As I wrote I'm using the April sdk.

Sorry I should read more carefully. The April SDK doesn’t work with Beta 2 because there were some changes.

You can find the June SDK over there: http://www.microsoft.com/downloads/details.aspx FamilyID=1FD20DF1-DEC6-47D0-8BEF-10E266DFDAB8&displaylang=en

why isnt the dxsdk on msdn yet

I am not sure why it takes so long this time. Maybe someone from Microsoft can tell you the reason.

As a matter of fact, I can: Technical difficulties.

The actual pages on the MSDN DirectX site were already created by me (I'm responsible for that website). However, there was a major change in hardware on the MSDN site that I didn't know about, which resulted in a several-day delay of getting the DirectX Developer Center updated.

All is good now though :-)

Hi,

When I run Direct3D 10 samples i get a message that says

This program needs to use the Direct3D 10 reference device. This device implements the entire Direct3D 10 feature set, but runs very slowly. Do you wish to continue

Can someone tell me why does it do that

Thanks

Simple really - there's no publicly available Direct3D 10 compatable hardware yet.

No existing hardware (not even your dual/quad GeForce 7900's or X1900's) has the required features to run a D3D10 application in hardware thus we've got to develop all code on the reference rasterizer for now.

Last I heard, Intel might be first out with D3D10 hardware (but no drivers until Vista RTM) and ATI/Nvidia will probably be along with some kit either late '06 or early '07. Start saving up now

Thanks,

So does this mean that the gpu is not used at all and all that rendering is done by cpu

Also, how does Microsoft develop DirectX 10 samples without hardware and get good frame rates Is there a way a work around to speed things up a little, or do they just use beefed up computers

It would be nice to have a gpu to test on though.

Yes - 100% CPU. This is pretty much the point of the reference rasterizer - its a reference implementation from which you can check your algorithms against. Hopefully less of a problem in D3D10, but under earlier versions you can use RefRast to determine if your code is wrong or the hardware/drivers are...

No idea to be honest... maybe one of the team will drop by and say

You can stream D3D frames either to disk or directly to a movie, so you write your code and leave it to render overnight... come back and see a nice "real time" playback.

Or maybe the IHV's have given them reference hardware and they just use that...

Get to the back of the queue

I think microsoft allready has some prototype graphic cards to render DX10 on :)
