With normal2x and normal3x interpolation, it does "nearest neighbor". WIth any of the others (such as 2xsai, and supereagle) it uses a special technique to guess the interpolated pixels in a way that does not smooth the brightness levels. However, I think linear interpolation would be good in some situations. So here I'm propoosing a new interpolation method in the next SVN version of DOSBox. It is 2x linear interpolation, and should be called "linear2x".

I assume you mean bilinear interpolation.
Which wouldn't be difficult to code, (I probably have the code of it in one of my local dosbox trees).
but is very similar to what the hardware opengl scaler does.

Have you added bilinear interpolation yet?

no, as i said. opengl does that already for you ?
Any reason why it isn't enough ?
