For ViewCaptureToFile, can resolution be set for raytraced?

Hi, as in the title, for raytraced, was there way to set the resolution to a lower than current output?
Say, making 4pixel x 4pixel as one pixel.
But ofcourse setting size as whatever wanted.

Purpose just to speed up render time but, keep same size output, as condition of accepting little less detail.

Should’ve tried that.
