I have Vista with SP1 and ran dxdiag and only still see DX10 not DX10.1.
I have a 8800GTX. Any ideas?:bigeyes:

As I understand it 10.1 it ATI's version of DX10. Simple as that.

10.1 was an update to 10 that Microsoft released as part of Vista SP1. ATI supported this update while NVIDIA chose not to.

They say that DX11 is a superset of 10.1 which means that it is a superset of 10 too.

You don't have that much improvements with the DirectX 10.1, DirectX 11 will bring pretty good ones, especially the tessellation tool and multi threaded rendering, increased maximum size of texture from 4ki*4ki to 16ki*16ki. To resume, very promising stuff.

Nvidia fully supports DX 10.1 with all the drivers since GTA iV was released...actually a couple version before then, and some betas also did.

This is a myth ititially started by ATi and their fanboi's and that advertising gimmick of a "DX 10.1" card...whatever that's supposed to be. There is no such thing as a "DX10.1" card. There might be cards that support it, but there is nothing that makes ATi special with DX10.1. Nvidia supports it fully on the current crop of cards.

My next video card upgrade will be in combination of the Win 7 release. I'm just itching to get my hands on some GT300 cards come end of year. My current system is tri-sli + 1 CUDA/PhysX GTX 260. Sure, a GTX 260 is massive overkill for PhysX, but I like the benifits to my folding@home PPD with the 4th GTX 260 in my rig. :wink2:

No, far from it.

What it does is it mandates 4x AntiAliasing. It also adds some tessellation functions that SHOULD have come with DX10, global illumination stuff,

The facts are also that nV does not FULLY support all DX10.1 functions. That is why they don't claim to.

It is also a fact that you dont see much increase with games that use DX10.1, because they are really not using them. DX10 is a nightmare. DX10.1 improves a lot of things, but is too close to DX11 for anyone to want to jump on it.

The biggest thing seems to be the 'free' AA.

Also, the FACT is the nV cards do not fully support DX10.1. That is why they dont claim to. What they do is support a superset of DX10 with the most popular DX10.1 features.
