Uploading a little modification that implementents, independently of the hard-coded normal scalers, the lossy interpolative scaling technique that is in favour with many gamers (see here, here, and here):
- upscale the image in a pixel-perfect manner so that its dimensions exceed those of the display,
- let the built-in bilinear interpolation downscale it back to the target dimensions and aspect ratio.
To activate it, simply use the overlay output in fullscreen and with scaler=none (see readme.txt).
The source needs some clean-up so I will attach it to the title post later. I still need advice on the preferred interface to these new scaling modes from the config file.
First, thank you for you efforts to improve this aspect of dosbox, one day I will throw my CRT....maybe.
Am I doing something wrong? It looks like billinear interpolation is completely off.
Look at 60/60 and the "Fog of War", they are uneven with this alpha3 built with the "overlay" setting.
640x480 on a 1900x1200 monitor.
Using "output=opengl" with "scaler=normal3x forced" is ever so slightly blurred but it looks even.
