Why Upgrade to DX9C?

Hey all,
I was wondering, what are the benefits of upgrading to DirectX 9C from 9B? Will it improve gaming performance? What is it going to do for me?

Thanks,
~sd

From my understanding it will help will FarCry and the latest patch 1.2, but that patch has been pulled b/c ATI's poor performance. Besides that, only D3 if it asks for it.

Nope, doom 3 runs on 9.0b.

Do the latest video cards even support DX 9.0C? or is it just DX 9.0A?

I installed DX9C, there was no performance increase that I could discern.

Thanks Force, I wasn't quite sure about D3 and I haven't bought it to see either. But mainly, if a game asks for a certain version of DX is when I install it.

I haven't looked over any documentation, again b/c I haven't installed it, but I think DX9c supports SM3.0. So only games that take advantage of it will benefit. (hence the DX9c and Farcry 1.2 game b/c 1.2 adds SM3.0 support)

It could have been just bug fixes. Not any real performance enhancements.

doom 3 asks for 9.0b, and comes with it if you don't have it installed.
