I'm not very good at taking notes from my experiments, but I used a large circle at 1024x1024 resolution IIRC. I didn't test with smaller circles, but I would say you're right as long as you're not turning vertex shader bound or triangle setup bound when using many smaller circles.

Yes, the big problem tree of Graphics Hardware/Programming always has a root called Performance.
But somewhere connected to that root there's a node called Developers And is here where, probably, DirectX 11 makes more sense.
Probably the final user only pays attention to the Performance stuff, but the Programmer, the Designer and the Modeler has a wider set o "things" to consider.

" (and i do think all g80 and above hardware can support DX11, though maybe not as efficiently) "
DirectX11 introduces some more pipeline stages. As you say maybe it's possible, but they would need to emulate, through software, to accomplish the same things ( I think... ).

Anyway, I hope that soon we all can get a DX11 card and take the discussion to the next level

I wouldn't bet money on it, Graphics is one of the most parallel things you can do so in the end your still competing for the same resources, but sure it's nice to be able to render from different threads, but in the end it's all the same.
Most new features in DX11 is mainly an update for the API and not the actual rendering process.
The only real "hardware" update is tessellation, while undeniably nice, it's nothing that can't be done with openGL, or Nvidia hardware (and i do think all g80 and above hardware can support DX11, though maybe not as efficiently).
The main point is that all features aside, performance is still key.

Yes, but tessellation is not the only new feature in DirectX 11.
What about Multi-Threaded Rendering?
I my opinion that will be one of the great features! Not only for games but also for scientific visualization
And remember that Multi-Threaded Rendering and Tessellation, are just two among others...

True, DX11 and tessellation isn't some magic new cool thing everybody instantly needs.
It takes times for these things to become widely used, so the real question is, whats the real performance of the card in comparison with the GT300 which comes just a few months(weeks even) after this one.

I guess this affects the workload of the rasterization stage and everything after that, not just pixel shading.

Also, It would be great to know more data about your experiment. I guess you were drawing a big circle, thus the small difference on the left hand side of the graph, because even the fan pattern yielded good quad coverage. So I guess drawing a lot of smaller circles would make the performance of the other two approaches fall even more abruptly with respect to your method.

Am I right?

meh - not exactly earth shattering. Without knowing the hardware involved (both CPU and GPU), it's just another tessellation demo...

Damn, the gameplay looks awesomely ridiculous, almost nearing DMC levels. I don't suppose it's going to have any form of multiplayer? That would be too good.
