I'm trying out VM Fusion for an old Windows XP engine as my latest Mac doesn't support a version of Parallels I have. 

The XP machine loads fine in Fusion but the resolution is poor - nowhere near as good as in Parallels. I have used the same Windows settings for the monitor (1920x1200) but the icons and apps look rather fuzzy and out of focus. It's usable but I'm wondering if there is a fix for this.
