Messing around with the gfxfilter settings in acsetup.cfg.

My understanding is that the default setting, gfxfilter=max, is a nearest neighbor scaler i.e. it implements the highest StdScale multiple compatible with your display.

For comparison:

gfxdriver=D3D9, gfxfilter=StdScale3:

gfxdriver=D3D9, gfxfilter=AAx3:

gfxdriver=DX5, gfxfilter=Hq3x:

(I can't post links directly, remove the spaces)

Edit: I managed to get the Hqx filter to work. Since it only goes up to 3x, I replaced the other images for an apples to apples comparison.

Bump for any chance of a dev response? I know shaders/filters potentially distort the artists' hand drawn designs but the standard nearest neighbor interpolation is also a distortion.

How so? It looks best to me.

looks better than antialiasing != not distortion of the original 320x200 art

The NN interpolation replaces every pixel of the original with a n by n block of pixels, n being the scale factor. This distorts the original image because of the jaggedness. Read the wikipedia article on pixel art scaling for a more technical explanation.

Clearly what "looks better" is subjective and people will disagree. But have a look at some of the other upscaling algorithms like Hqx and xBR/xBRZ in other programs and you might wonder what this game would look like with them too. Now xBR/xBRZ is not yet implemented in AGS, but Hqx is supposed to be.

Well I don't have distortion because I'm playing in windowed mode.

As in, you're playing in a 320x200 window, no scaling? If so, that's great if it works for you.

But I suspect that's not what you're doing. Is what you're trying to say that nearest neighbor interpolation is not a distortion _because_ it's in a window? Are you confusing aliasing with aspect correction?

I use the default settings, which are windowed mode with max nearest neighbour. So the graphics are not antialiased and the aspect ratio is preserved (the pixels are square).

This is as opposed to full screen nearest neighbour which, depending on your monitor, either doesn't keep the aspect ratio (the pixels are rectangular) or keeps the aspect ratio but with some blurriness (because the pixels are not scaled up by a factor of two, unless your monitor resolution is a multiple of 300x200).

bump for adding Hqx comparison. It's smooth. AAx3 is pretty blurry compared to Hqx.

The opinion of our artists is that the game looks best with the Nearest Neighbor filter, and we recommend that you do not use the other ones. But hey, it's not like we're going to send an angry frost giant to your house if you do anyway
