I think it has something to do with the fact that there are currently no Dx9 drivers for the Parhelia and Displacement mapping is an implemintation of Dx9.

That doesn't make any sense. The demo is on the Parhelia CD.

There may have been hacks in the early drivers and the DM demos may have been written specifically to use them under dx8.

As they progress with driver versions I suspect (as the DM demos will be the only programs to use the dx8 "hacks"), that support has disappeared, and will reappear in the dx9 drivers. The DM demos might well work then, possibly with an update/patch to them.

Try running the demos using the drivers from the original Parhelia CD.

It's not really a hack! Matrox were open to say that DX9 wasn't specifically needed for DM on Parhelia. So, they'd obviously done some sort of SDK (i.e. it was planned and didn't just 'come about').

Rebooting could suggest a whole load of issues

matrox glide?

From my (admittedly very limited) understanding. The Displacement Mapping is a feature much like EMBM when it first came out, not necessarily part of DirectX at all, but an nice feature that could be enabled through a patch. I also recall something about the Displacement Mapping in DirectX9 was licensed from Matrox. So basically it's not a DX8 feature and only added to DX9 by MS because they thought it was a cool feature that Parhelia has. From what I've seen the Parhelia is the only one that can support it in Hardware anyhow, so who knows how much this feature will be used.

I thought the R300 has support for Displacement Mapping...

I'm gonna go out on a limb and say it has to have it as it's a DX9 part and it's a required feature of DX9.... hey, could be wrong tho!

The R300, has hardware assisted DM. Only Parhelia does the real thing.
