Dissidia 012: Duodecim Final Fantasy

As mentioned in the Github thread, turning off buffered rendering "fixes" the overbrightness and some other graphical artifacts I have - some stages have a "flickering ghost image" effect, and many HP attacks cause the screen to break into segments with each segment flickering a bit.
(Edit: I think the word for the artifact I was experiencing is "screen tearing.")

"Posterization" means converting a color gradient to distinct regions, each with their own tone - think about what happened when you converted a picture to GIF or some other 256-color format from 16-bit color.
