I've been running X2 Producer with no problems at all.  I can add tons of plugins and everything works great.  I'm running Windows 7 64bit with an AMD Phenom II quad core 2.9ghz and 16gb of ram and an Edirol M-16DX mixer/interface.  When I installed X3 Producer and opened a project I was working on the cpu meters nearly maxed out and playback is terrible.  I removed almost all of the plugins and got it to work (more or less).  As soon as I added Slate Digital FG-X the CPU usage jumped way up.  With each plugin I insert or enable on the pro channel my CPU usage increases dramatically.  X2 never acted like this on my system.  I went back to X2 and everything runs perfectly like it always has.  Maybe X3c will make it usable on my system.  Right now I'm feeling like I wasted $150.  Any upgrades with X3 are apparently lost on my system.

Have you verified X3 is using the same ASIO buffer size in Audio Preferences?
 
 

I just happened upon the fix.  I turned off the VST background scan and set it to scan on startup.  Oddly enough that seems to have eliminated the problem.  Thanks for the response!

Well, I got my hopes up but after running for a few minutes everything froze up and became totally unresponsive.  I had to use the task manager to exit the program.  Back to X2.

Glad you got it sorted, but you should really contact Tech Support or file a problem report so the Bakers can look into it if there's a persistent problem with background scan on your system. In the long run if you can get it working right you'll lose less productive time waiting for unnecessary scanning on every startup to complete.

I emailed them about a problem twice last week.  No response.  Now when I open X3 my audio interface doesn't even show up.  X2 still works perfectly.  X3 is not looking like it is worth my trouble.

That really sounds like a driver issue to me.  Have you tried reinstalling your interface's drivers?

Just out of curiosity, do you have your system "tweaked"? Like services disabled and the like? If so, I would recommend changing it to a normal startup scenario and see if that helps. X3 is worth the trouble, and there are alot of really good people on this forum who can help. Just hang in there. :)

The whole "tweaking" thing causes so many problems..

Yup. Messed myself up more than once. :)
