Reading the github issue, it's understandable why it got removed.

If discussion on this functionality for this other project needs to occur do it elsewhere (preferably not vogons), this thread is for DOSBox ECE.

Yeah, i meant your pixel perfect shader in previous post 😋

Both your screenshots are truly pixel-perfect, with 2x2 square pixels and no apsect-ratio correction. The original resolutions are 640x400 for the first and 640x480 for the second screenshot. The first one has PAR of 1.2 (5:6) and should aspect-corrected if the output resolution permits, which in you case it does not. I am glad the pixel-perfect shader works at least in this situation, but the reliance on the GPU for so simple a thing as pixel-perfect scaling seriously raises the requirements for a DOSBox machine... I should like to see the pixel-perfect shader at work with a 320x200 program on a 1650x1050 display, where it should figure out to use 4:5 scaling, because 5:6 will not fit.

DosFreak, I bet your pardon for replying—didn't see your post.
