Catalyst CC upgrade - Why does option disappear?

Why does the option disappear,
'Scale image - maintain aspect ratio' if I upgrade the CCC.
I uninstalled it and put back the old one.
Possibly something to do with having the mobility ATI card.
But I have researched this aspect ratio thing a bit, and it seems
to depend on system configuration. And ATI cards are known
for not having this option.
I find this option very useful. Games always go the height of the screen,
and I can see 1024 X 768 resolution full size if I need to.
