Some games lost compatibility with the 174 series for me. Most of them are really old game, but City of Heroes doesn't start at all either now.
(too bad, I wanted to give the free trial a go to pass time)
There is a small indie game who doesn't seem to detect the card (or to detect the support of shaders) with the 174 series too. But considering how it's a small indie game, I'm not too surprised.
