Cubase 7 64bit VST Instrument GUI slugginess

Cubase
1

For some reason I am experiencing a problem with Cubase 7 64bit (latest version) that some of my vst instruments are behaving in a way that the GUI is very slow and sluggy. I am experincing this with Spectrasonics Omnisphere for example, it takes me around 7 seconds to see a patch list whereas in 32bit cubase it takes only 2 seconds.

Strangely I am not experiencing any of these problems in 32bit version of Cubase, or in any other DAW I’ve tried - only 64bit version of Cubase seems to be causing slugginess and hanging.

Any idea how to start troubleshooting this??

Are the plugins you are using bridged?

3

No, they are 64bit such as Omnisphere.

Did you try to start Cubase in safe mode and/or remove preferences?

I haven’t tried that yet, could you instruct me how to start cubase in safe mode, or how to trash preferences? Thanks for the help!
