Also, AMD HD7xxx series GPUs have some problems with the D3D11 backend, so you may want to get an HD6xxx series card instead.
Four questions, does the 7xxx series perform great on D3D9 backend? And the only difference between D3D9 and D3D11 is that D3D11 is a bit more accurate?
Can the D3D11 issue be fixed with a driver update?

Also, how is 7xxx series performing on OpenGL? Smile
The 7xxx series performs more or less as you'd expect on D3D9.

There are some games that are more or less unplayable with D3D9, and you'll have to use D3D11 or OpenGL for those. Some of them may also be broken in OpenGL too, forcing you to use D3D11.

No, no driver version has fixed the issue yet.

I think it's a little slower than D3D9 and D3D11 for all GPUs.
AFAIK (ALL: please correct me if I'm wrong ) i7 only has HT where i5 does not. Also in most cases i7's seem to have a higher MHz. HT does not help us much at all. Its more for things like video editing.
--Oh wow I missed page one LOL, so yeah you know that already--



only thing to add to the post above is that D3D11is not really "BETTER" per-say just newer. it has more support for things like shaders and effects for the DX11 cards. So no it does not preform faster, its actually slower in some cases. If you need a performance boost get a faster card or CPU. I find DX9 runs just fine and as mentioned. I use DX11/OGL if 9 fails.

Thanks for the answer.
As you'd except, would that mean 3xIR, 4xSSAA and 16x AA? Smile

But, on the last question, I didn't ask if it was fixed, but if it's fixable with a driver update?

The Dolphin description says that OpenGL and D3D11 are slightly more accurate than D3D9, I just wanted to confirm that Smile
It may or may not be fixable with a driver update, but if it were, Dolphin has no way to complain to AMD and make them fix it.

Also, D3D11 and OpenGL are generally more accurate than D3D9, but in some cases won't be.

Some games need DX11 or even OpenGL to work properly. But DX9 is enough for most games

Fixed that for you.

I'm pretty sure the 6000 series has the same issue. The guy in the thread that you're thinking of compared an HD5000 series card against and HD7000 series card.

Are you referring to d3d11 and d3d9 in general or the backends used in dolphin?

Either way you're wrong. Sometimes the d3d11 backend it faster, somtimes it's slower.

In the context of other applications d3d11 should always be faster than equivalent d3d9 code as long as it's properly optimized. The exception to this is obviously certain things that have no d3d9 equivalent.

Yes in some cases not all. My point was speed. Though like all here said, just try each one for what you desire more.

Quote:Either way you're wrong.
If you have a DX11 card with DX11 backend and code designed to use DX11, then yes I would not disagree.
If you have a DX9 card with DX11 backend and code designed to use DX9, I do not agree.

I dont know enough about dolphin to know what is going on, but my point is the Simple, using a higher DX is not necessarily going to give you better performance. Sure some DX code may have been revisited in later releases but its main goal is to support the new technologies in the card.

You can't run d3d11 code on a d3d9 card.

Also what code are you talking about?

D3d11 has an entirely different and far more efficient shader language. It's better in every way. I have no doubt in my mind that if the d3d11 backend was as well optimized as the d3d9 backend it would always produce better performance even with additional shaders for effects that can't be emulated with the d3d9 backend. I think this is what you mean to say but "designed to use" doesn't really make sense. Anything that uses d3d11 is designed to use it.
