what do they do? I can't really tell the difference between them. Why should I use anisotropic filtering over point filtering, or vice versa. If anyone has any links to info about them, let me know. sad.gif

why search google when you can ask your emulator specific question in a bloody emulator board? besides, an answer to that question wasn't really in those links. he said he saw no difference between any of the hardware filters so he was wondering what the advantages were for using a superior hardware filter on that emulator when you don't even see a difference.

I did google before I asked the question. I know the difference in the filters in 3d scenes. But in 2D sprite based games like on the SNES or GBA I can't really see what the diff is. Why should I use one over the other?

anything above point filtering will 'smooth' the image.
linear - just basic bilinear blend

gaussian - applies a gaussian blur filter. so will smooth more if thats what you like

quincunx - weird multisampled antialiasing that blurs textures in 3d games - its advantage being speed. Though afaik all hardware filters run at the same speed so this one is useless.

anisotropic - used in 3d for properly filtering textures slanted at a distance from the camera. Can't see its use in 2d though.

I'd go for linear or anisotropic myself. The others in theory should be alot blurrier than is necessary.
