Sacred Gold runs at 1024x768 by default, so on widescreen monitors, it will definitely become distorted. One thing you can try is to enable the setting to keep aspect ratio intact. Most drivers should be able to do this (yes, even the lowly Intel integrated graphics).
My AMD driver allows me to enable GPU scaling for the monitor, so I can choose these 3 options:
"scale image to full panel" - default normal behaviour
"maintain aspect ratio" - scale image to full panel but keeps the aspect ratio, resulting in black bars at top-bottom or sides
"use centered timings" - centers the image without resizing, keeping a physical pixels equivalent to an image pixel, so black bars will be all around the image, unless the image is at native resolution
