Hello everyone,

I love scaler effects (HQnx in particular : HQ2x : different versions ? )

I just want to say that two scientists kopf and Lischinski have created a very interesting new scaler algo :

I hope there will be some implementations soon that could be easily integrated in Dosbox 😀

Right now this scaler is not practical as it is only for stills and not for real time scaling. Afaik someone IS working on doing it real time but expect CPU usage to be very high

Indeed. According to the Results in the paper, it got a median of 0.62s per frame. Needless to say, DOSBox would be very slow with it, and totally unplayable.

Microsoft has its name on it - good luck trying to use it in something like DOSBox (even if it was fast enough for realtime)....

it does look pretty damn good though!

I'm a bit annoyed by the comparison shots. For HQ4x it looks like they applied the filter once and then scaled up the image by 4x rather than reapplying the HQ4x to get a 16x increase.
