If you have long load times later in game i found out one way to help.
I had like so many saves i always do new save i i save not quick save and apparently it made loading long so i deleted like 10 saves and now have 1 and loadings are not cut in half.
Mmm, not had an issue with long loading yet as I always install to HD. But will bare that in mind if it does start to slow down, but certainly I would not work from 1 save only. Far to risky with regards crashes, glitches and 'Doh!' moments.
I have it installed but i was still experiencing load times so long.
It like farther you get and more choices you make the longer the loading.
Not sure what's wrong with yours then. I told all of my friends to do this and like me their load times are the way they should be... short. A few people that have seen my post had their problems solved as well.
