Don't we all love it when some people are reporting breakage and some people are reporting "works fine here"?
Might look at it once I got some spare time again...

^^ well, in some games it does break stuff for sure, but it's only some and the benefit in others is nice cuz there's quite a lot of 2D-surfaces in GC and Wii games.
So it would be nice to have it as an option

@NeoBrain
You mention the major bottleneck of Dx11 is in the common video plugin, and very hard to fix, so is it like a weakness in the common video plugin's general design, and needs full rework or something? And is it possibly also causing the huge speed difference between Dx9/OGL? I'm asking since there's been lots of optimization work on the core/JIT stuff lately, unlike with the gfx stuff, which is the throttle of many slow games, so I was thinking maybe gfx related optimizations requires some really dirty work to be done...

Yeah, it would help if they stated their specifications and configuration. It could very well be an issue with their hardware, drivers, or configuration and not Dolphin itself. It could be an issue limited to specific hardware, like Nvidia specific or ATI specific issues in the past. 08-27-2010, 05:32 AM

This is also done in DX9, but the problem in DX11 is that we can't PARTIALLY update a vertex buffer, i.e. we can only update the whole data. I've added an algorithm to make this less dramatic, but it still is quite a dramatic performance hit, since we're wasting up to 100% more bandwidth. Even minimal vertex buffer transfers are 0x500 bytes big. It wouldn't be THAT bad if we were able to load the vertices directly into the transfer buffer, but that's not possible right now in VideoCommon. Anyway, I guess this isn't related to the difference between DX9 and OGL (if it was, people wouldn't always say "not sure were the difference is" ) 08-27-2010, 06:32 AM
Maybe if Marcos or Rodolfo can fix the bottlenecks with GPU emulation as mentioned in issue 3081 the DX11 plugin might benefit as well.

I get this error using the Directx11 Plugin.
"Failed to find a supported video mode. Failed to initialize Direct3D. Make sure your video card supports atleast D3D 10.0." I have a XFX 9800 GTX+ which has DirectX 10.0 support. I am using Nvidia drivers 258.96. Running on Windows 7 x64. Is there anything i need to be aware of when setting up Dolphin configuration before i start a game? 08-29-2010, 11:51 PM
install latest directX (June2010)

Directx is getting a loads of updates since directx11 cards are new. Scary.
Thanks. 08-30-2010, 02:48 AM
Nah, I think there always were like 2 new versions each year...
