Still testing, not 100% shure, but with latest Waves bundle + HD6400 driver + windows 764 bit auto-update, hang on exit seem disappeard.
I now have quite frequent crashes to desktop on Mac after the latest update.
Seems to be when iām using Native Instruments stuff like Guitar Rig or in the case just now Kontakt
When in the name of god they will fix it!!!
Iāve a project with Kontakt 5.5.2 and it crashed a lot, even with small samples from Nativeā¦
I noticed that Meldaproductions tend to crash cubase a lot.
Iāve had Melda stuff conflict with Waves quite a lot in the pastā¦ since the last waves release it does seem to have calmed down a littleā¦ when i have time iām going to see if the problem is still there or just lurkingā¦ do you have Waves on your system?
I have some but iām not using it. Cause their laggy interface is killing me. 
I noticed that sometimes even empty project with a single melda plugin can crash on exit or on removing plugin from the channel ( by drag and drop)
Itās absolutely heart breaking to set up a bunch of tracks, edit a bunch of midi drums, setup guitar tracks, record a few tracks, change some tones, jam, find something you think might be the start of something new, stop playing then BANG.
Cubase disappears and you send an error report to Apple.
My response would have been hilarious for youtube had I been recording it but man does it flip the anger switch.
It must be system-specific ā¦ I usually have several Melda plug-ins open at once in small-sized projects (e.g., 2 or 3 VSTiās, 10-20 audio tracks, many with un-bounced VariAudio edits active) without crashes.
They should do like Bitwig and make the plugins independent from Cubase ā¦ in bitwig if a plugin crashes, it tells you what plugin crashed and ask you if you want to reload it or close it and it doesnāt affect your session at all 
I also have no issues with Melda Plugins, but there should be an update (9.20) soon that fixes an issue with cubase.
Hi
I used the old NVidia drivers and parking core trick and all worked fine until I upgraded to 8.0.15 and latest NVidia drivers. Then I started to have peaks and crashy exit and even a strange audio sync issue as someone stated before.
In my case I re-installed the old but trusted NVidia driver,and did the video acceleration tip stated before and all is back to normal.
No more peaks,nor audio artifacts and a normal and fast exit.
So the problem must be video card related.
which driver version is that?
Does anyone think that using 32-bit plugins might add to the problem?
defaults write com.cubase.common GraphicsAcceleration 0
Also, how would I undo this command in Terminal? Retype, changing the 0 to 1?
One more report.
I figured out that slate digital VMR was causing crashes on exit in my case. Iām at their beta test team, they have fixed this issue in the latest release 14010
I run my now rather old GTX 670 with the newest driver available. No problems with Cubase that I could attribute to Nvidia so far.
Probably upgrading it to a GTX 1070 when they get available.
Iāll report back if it is a horror show
(YOSEMITE)
-bash: read: `com.cubase.commonā: not a valid identifier
Soā¦ Iāve tried all kinds of tricks now. Iāve got an nVidia card so Iāve checked my drivers and Iāve tried disabling acceleration for Fabfilter plug-ins (according to their workaround) and so onā¦
Even though there seems to be some confirmation from Nvidia on at least one DPC latency bug I donāt think this is the root to my problem. (From what I understand there was a DPC hotfix for Windows a while back and itās now included in the latest drivers Iām using.)
I got a feeling that the problem Iām experiencing is related to the Windows 10 Anniversary edition (aka Redstone) and the latest Cubase 8.5 Pro version not getting along so well. My problems started after Redstone and I got bad ASIO performance and the āRecording error : Audio dropout detectedā-error when recording, something I canāt remember ever having any problems with.
Sincerely

Yes I can relate, after the Redstone update the performance is very poor, with a lot of crackles and dropouts no matter the ASIO settingsā¦ Just before the update my very same project worked flawlessly. After the update, without having altered anything, I canāt even play a single VST without a dropout.
I really think it is the W10 update to blame for all this.
I am having the same issue. As soon as I include virtual instruments in my project itās all over. Massive disk load and lots of audio drop outsā¦ I tried some of the solutions on here and while it loaded a little faster, the lag time still persists.
