My game uses 320x200 pixels, but this is scaled up to any screen size using DXDRAW.Options.doStrecht. Here the pixels are interpollated and it looks very blurry. I'ld like to have clear pixels instead (in OpenGL this would be like using GL_NEAREST instead of GL_LINEAR).

Is there a way to do that in DelphiX?
(I'm using an old version of UnDelphiX from 2001).
