I am up to intermediate lesson 4 and Chili gives an excellent explaination of directx and how the GPU and VRAM works with RAMDAC to flipflop the page buffer and he mentions 'Bit Blitting'!
Awesome!
A part of my project is to demonstrate sprite blitting, I think I'm getting a better understanding of it.
I'll report back when I get to the point of writing the damned thing. I'm just getting my framework together.
