Hi Guys, Just wondering if anyone knew off the top of their heads if any of the basic functions used to create a device and present a scene have changed dramatically? I am pretty sure the GetBackBuffer now has an extra parameter, which is why i ask. I am also getting a problem of random colors being blt''d to the screen whenever i present the backbuffer. I understand i am being vague without posting code, but thought someone else might have had the same troubles and saved me trekking through the SDK for each func. Thanks AFace
