[quote name='sony']I have the update so I decided to test it out on 6 games.
Forza 2 went from 5.3gb to 4.7gb (-11.32%)
NHL09 went from 5.7gb to 5.0gb (-12.28%)
COD4 went from 6.7gb to 6.5gb (-2.99%)
CODWaW went from 6.5 gb to 6.4gb (-1.54%)
Sacred 2 went from 6.5gb to 6.3gb (-3.08%)
Left 4 Dead went from 4gb to 3.7gb (-26.00%)
Total savings = 3.1gb
Overall, it seems like reinstalling your games is only worth it if you're near the brim in terms of free space. The total savings was only 8.68% for the six games I tested. So just extrapolating from this for 100gb I'd save 8.7gb with the new installation sizes netting me an additional game on my 120gb. Other than the huge gains on smaller games, it probably isn't worth it to reinstall everything.
edit: decided to test the only "small" (3.4-3.5gb install) game I have.. Earth Defense Force 2017 went from 3.4gb to 1.6gb[/QUOTE]

I wouldn't go around thinking lawsuit just yet. My guess is that because of the upcoming Games On Demand service, the research devoted to that made them reprogram the dash in such a way as to ignore security and dummy files used on DVDs for loading purposes. The old dash probably wasn't designed to read those images without the files, thus the large file sizes.
I'm going to continue testing the games I have today and check a few of them for any performance gains. Again, based on the few I did last night I think that performance will be the same as before but I just want to make sure before making that theory a fact.[/QUOTE]
