z-buffer problem

[Zviri]

Hi
Im making an program using Microsoft Visual c# 2008 EE / directX sdk 2008 (november) the program is working great but on many other computers mostly with integrated graphic cards the program breaks down and it isnt working until I stop using z-buffer which I need....
I tried to create a device : deviceType.Reference instead deviceType.Hardware but it is still the same.

Is there anithing I can do with that? thx

if it is necessary I can upload the whole code / project

update

Ok I can fix it when I use deviceType.Reference but then it is needed to be a directX SDK installed on the computer and thats not very applicable.

thx

Re: update

It could be a driver issue on the target machine - have you tried updating the drivers on one of the failing machines just to see if this fixes the issue?

yes, but no change, Ive tried to use different frameworks 2.0 , 3.0, 3.5 different versions of directX but no use

What happens when the app fails? Are you given an exception? Does it have a DirectX error code?

 

[Zviri]

no just application error ....

Ok Ive fixed it.
It was a very trivial mistake I didnt set the BackBufferFormat , with a 16 bit R5G6B5 format it works perfectly
