Very stable here, I'd say as stable, if not more than X1d is/was.
Note that I'm using the "studio" edition, and I'm fully aware that most major "improvements" from X1 to X2 are things that are not included in the studio edition (prochannel, etc....) so that may explain why it very robust,
I have this issue with NUDGE (opened a thread about it, and contacted support, no answer yet), I have this issue on 1 system (my other system runs fine)...
I just finished a 6min cue to picture, about 20 softsynths, crazy automation and stuff... on X2A 32 bit ... never failed on me,
once I got over the new ways of X2, I "forgot" about the machine... X2 runs smooth, I completely trust it. (unless I nudge clips!)
Like I said in a previous thread, Studio edition lacks the initial value it had, it feels a little left out, for the price the upgrade costs,
but in NO way I can relate to the problems and overall bad reception people have expressed on this forum.
I wonder if there is anything to do with the fact that the upgrades are now downloadable, and more prone to some data corruption...
Cake should add (or improve if it's already there) a validation system on downloaded files. Maybe that would sort some issues.. Just sayin'
Cheers !
