You don't like following links, do you ?

Especially with high scaling factors, it can give a very smooth looking image.

HQ-Lite : This is a variant of HQ : the resulting image is close to HQ, but it is calculated a lot faster. It has a good quality per CPU usage ratio.
Apparently a faster (experimental, promising) HQ filter, which seems to be an Open-MSX exclusive, but as the licence is GPL it shouldn't be too bothersome for Toni to grab it from the source code, and adapt it to WinUAE.
