Grease Monkey will also compare the Direct X version and video drivers that a 
system is using to the latest available versions.  This screen works 
identically to the game tracking screen, with the interesting addition of a set 
of personalized benchmarks at the bottom of the screen which show how your 
current set of drivers compare with previous versions on some of the latest 
games.  Not overly relevant, but certainly interesting to peek 
through.  

The 'version management' option available in the dropdown box gives you 
download access to older driver versions, which is useful should it become 
necessary to revert your driver version.  

Downloading demos and add-ons with Grease 
monkey      
The 'downloading' tab is really present for one reason only:  to keep 
the hardcore gamer from getting bored!

As you can see, this tab has several categories to choose from, the main ones 
being 'demos', 'mods' and 'maps/expansion packs'.  As you'd expect, each of 
these buttons leads you to a screen where you can download recent demos, mods 
maps and expansion packs for popular games.  

   The demo screen 
was impressive, with the latest and hottest  demos being featured on 
the front page while an alphabetical listing points to the rest of the 
games available. The  selection is not exactly comprehensive, and it doesn't go too 
far back into the past, but that's not   really 
relevant when you are talking about game demos.
