[DUPE] GUI lagging when moving or resizing parts, C8.0.20

I have posted about this issue before, but since there is no official or “correct” issue report about it I thought I’d make one. It is about the very obvious GUI lagginess/latency that I’m having when performing the most fundamental maneuver in Cubase: Resizing and moving parts.

This applies to Cubase Pro 8.0.20 under Windows 7.
If it is of any interest, I’m using a 2560x1600 Dell Screen and an Nvidia Quadro NVS295 Graphics card.

Steps to reproduce:

  1. Open Cubase 8.0.20
  2. Open any project that contains 20+ tracks
  3. Drag to move or resize any part. The overall feel is sluggish.
  4. Open an earlier version (6 or 7) on the same computer.
  5. Open the same project in this version and try the same thing - much faster and snappier.

I have made a 40 sec video here in order to describe the issue in detail, where I compare with the feel of Cubase 6.5.5 on the same computer. Please take a look at this: https://youtu.be/_OIjk9dUncI

Thank you,

Hello,

This has been reported before, it is nested under the same issue as this one: http://www.steinberg.net/forums/viewtopic.php?f=231&t=71652

With or without a video Cubase GUI seems to lag with big projects.

Best regards,
