I'm pretty sure I read on an NVIDIA presentation a few years back that the vertex cache only works when using indexed geometry. I guess this is still the case.

But I may have missed the point, since your post is very brief! :-)

I enjoy reading your journal BTW.

Why can't you use queries? I have a 6800 GT with retail drivers (84.21) and I use the VERTEXSTATS (only works in d3d debug) and OCCLUSION queries. I haven't tried any of the other ones though, are those what you don't have support for?

That would be true (if you think about it, it cant possibly work with non-indexed). It is also part of the point of this entry...

I specifically kept it short-and-sweet as an indication of things to come [wink]

Excellent! Hopefully have a more in-depth and interesting entry in the next couple of days...

If I call ::CreateQuery( <id>, NULL ) I get E_NOTAVAILABLE - which, as per the docs, indicates that you cant use that query.

I'm pretty sure I've got both of those queries, but sadly neither of them are what I want (I want release/retail info) - I particularly want D3DQUERYTYPE_CACHEUTILIZATION, D3DQUERYTYPE_VERTEXTIMINGS and D3DQUERYTYPE_PIPELINETIMINGS.

Cheers,
