Laggy Wave/audio (zoom) handling

When you load up big wave files the zoom gets zo Laggy.
It’s not snappy anymore and kinda annoying.
My only cure is to make the vertical zoom as small as possible.

Any other way to speed up Wave/audio handling?

This has been from cubase 6 I guess all the way up to 8.5 :frowning:
On all my computers…
