DrawIndexedPrimitives problem

Hi,

I've got some polygons being drawn with the simple shader using DrawUserIndexedPrimitives(...

This works fine on my main laptop with a GForce 7800 card,

however I run into problems when I try and run on the same exe on my Samsung Q1 (Intel 915G card, dx9 compat with latest drivers and dx 9.0c).

The problem is that it only draws polygons that are intersecting either the front or back clipping planes.

DrawUserPrimitives however work fine.

So I'm at a loss as to what I'm doing wrong.

I've tried setting wire frame / alpha blend / scissor rectangles but still the same.

Any ideas ?

Cheers,

Steve.

This could be a bug in our product. We don't have a Q1 to test against, but I am sure a few people here have one :-) Could you please file a bug for this on Microsoft Connect? http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=682921&SiteID=1
