Direct Draw Palette Hack

What exactly is this? Could It be used to make sprites from other palettes look better?

No, It just has to do with some graphic card issues, I believe. I have to use it on my aunts laptop, otheriwse the colors go all over the place. For instance, the doom guys hand is purple and it'll jump around colors when you start moving. Once you put it on, the game should react normally. I could be very wrong and just switched some other option to fix it, but I'm pretty sure I'm right.

I believe the DirectDraw Pallete hack refreshes the pallete every frame so it doesn't get corrupted in the video memory. It makes ZDoom run a lot slower for me.

You are correct. "DirectDraw palette hack" causes the game to reload the palette every frame. Normally, the palette is only uploaded when it changes, such as when you pick something up or get hurt. However, some video cards will randomly mess up the palette, and the only way to fix it is too upload the palette every frame. (And in some cases even that won't work. I once had the "pleasure" of using an old Trident video card that made random colors blue every single time the palette was uploaded, so it never had the right palette.)

Would I be right in saying that it's just to maintain compatibility with older cards?

Not older cards. Buggy cards.
