I've been running X2 really hard the last few nights.
I only used two effects outside of the Pro Channel.
Everything is working awesome. No Pro Channel problems, no lockups, nothing. And ... I've been using the cheapo embedded sound card on my mother board.
I added a PC effect just now and started getting stuttering. Fine, I'll just go in and raise the buffers a tiny bit.

BOOM! LOL!!!!!!!!
It fried X2. It crashes when I try to play a project now. Tried the different driver settings, asio, mme, etc etc ... I know it's the crappy sound card that caused this, but now I'm forced to do that fresh install.
At first I was getting errors that said it was one of the effects I was using, so I removed it. Then I started getting StackHash errors and then Win7 stepped in and said it was forcing me to run it in some kind of compatibility mode. From past experience, I know it's game over at that point.
So far up to this point though, X2 has been rock solid, even on this little crappy embedded sound card and I really have no complaints. I was intentionally pushing it to see what it would take to break it.
