So far, we've managed to fix problems on systems that have sluggish performance by tweaking the graphic settings. Could the people who have problems please let us know that they still have the reported problems if they put the settings on low ? Not that we'd want you to put it on low if your system is clearly capable of handling the game, but we'd like to isolate what's causing the problems reported here as we can't reproduce them on a variety of hardware. We'd very much like to provide fixes if they are indeed related to the game, but we cannot configure every single configuration out there.
Regarding the 360 patches - we have a patch in submission for the savegame issue & are awaiting feedback from Microsoft. We are also working on 360 patches for the other versions but don't have a shortcut for getting them to you, much as we'd want to. In case you're wondering, we're not going to let you down on this and are endeavouring to get them out. As a matter of fact, we actually had 360 patches ready for day 1 release, but the path between Larian and your 360 is unfortunately very long.
