Why Upgrade to DX9C?

[swampdonkey]

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,

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. ;)
