I have similar problems: Massive ASIO spikes in Cubase when I load a Play 4.1.5 instance and move the mouse. It is sufficient to load Play, it is not necessary to replay a track with Play to get the spikes. Renders any project with Play 4 unusable, very annoying.
Do you use the iGPU, the onboard gaphics of the i7-4770K? I'm asking, because I use the iGPU of my i7-3770K and suppose it's a combination of the brand new Play Version 4.1.5 and newer intel graphics drivers.
I don't even have to move the mouse wildly around like you did in your video. I get an ASIO spike every time - no joke - the shape
of the mouse cursor changes. This happens at boundaries of GUI elements in Cubase 6, 7.06 and 7.5, but interestingly also at GUI elements of the windows desktop.
- I don't get those ASIO spikes with Play 3.0.47
- I don't get them with Play 4.1.5 if I uninstall the intel graphics driver and use the generic VGA driver of Windows 7
- I don't get them if I install a very old intel iGPU driver from 2012
- Some others say they don't get spikes with Play 4.0.23, which unfortunately is not available anymore
So it's definitely not the mouse driver, it's ... Hmmm....In the changelog of Play 4.1.0, the version following 4.0.23, I read
* Fixed graphical glitches in envelopes
* Fixed interface flashing/crashing when switching to Player during load
That is sufficient to propose my conspiracy theory: Problem with Play 4.1.5 and intel graphic drivers. Not a problem with Cubase. Okay, Cubase could still play a role, could be a combination of all...
For the time being, I use the very old intel graphics driver and hope for a fix, which, I fear, may take a long time. I guess East West will blame Cubase, never blame intel (and if, intel wouldn't care). Should they blame themselves? I don't know.
