Pixel pipes: 0x00000001 woohoo Good? yes very good if it was 2, it would be like gc2000, which is not supported yet (which does split-framebuffer rendering, which is kind of annoying :-) I'm not sure what that is, but it sounds scary well everywhere you normally have to pass one pointer, you have to pass two, each "pixel pipe" rendering to its own half which brings all kinds of fun alignment challenges huh it's like SLI Is each one physically mapped to half of the screen? I see yes it's subdivided, and the final resolve step combines them and there seems to be no way to turn it off so there's no half-performant half way It's not possible to run in a mode where one of the pipes is disabled? nope! :D fun well maybe it's possible but I'e not found it I guess it'd be possible to ignore the output from one of the pixel pipes
