Rendering with 2 and more GPU.
I Know it is not connected to Dxwnd fuctionality, butmaybe you want to make it, if you want, please read further.
As i know then D3D(9\10\11) program start, it enumerate GPU`s then\if it find aprorite GPU it look for needed resolution and color format, then it make surface\back buffer and start to render to it.
(info from this book : http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/)
Can we make (or use dxwnd as) proxy and alter above routine to split surfaces\back buffers to 2+ gpu ?
Author of book write that rendering can be done to isolated part of screen so it look like it is possible. If memory pool will be managed, there will be no memory corruption problem.
So this will be software SLI or something like this.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Very interesting, but until I get a multiple GPU video card (I even doubt I'm having a single one right now....) I can get of no help, unless someone would like to build some functionalities that I could integrate in DxWnd for ease of use.
I guess the main trouble about this, apart form finding the real coder, would be the blind integration of code in DxWnd to be shipped to someone else for the necessary testing.
But you never know. My PC is becoming old, who knows ....

Hope gho has a powerful testbed with 2 or more GPU ;)
i have two gpu nvidia but not compatible with sli and on othr hand sli have many glitches

me too have old pc. i have one integrted video card 8100 Nvidia and nvidia 210 (office level card) so it is bad..
Maybe something like dev enviroment and remote access to my pc ?

My video card is an ATI Radeon HD 4250: just forget it!
I'll try to find a better way...
