Diva extremely poor performance in Cubase 8 compared to Cubase 6

Hi all, hope you can help me as Diva is my #1 go to synth. I upgraded from Cubase 6 to Cubase 8 and decided to do a performance test. I created an instance of Diva playing a 12 voice synth patch on some recorded midi, then duplicated the instrument channel many times over to test how many I could run before the Asio meter blows up.
In Cubase 6 I was always able to run at least 20 instances of Diva with this patch without issues. In Cubase 8, 4 instances of this normal patch bring my computer to its knees.
Any ideas what the issue could be? At first I thought it was Cubase but then I performed a similar test with many other VSTs and had no problem. I can run 50 instances of NI Massive for example.
Here are my specs for both tests:
Windows 7 64 bit
Cubase 6: 32 bit running Diva 32 bit
Cubase 8: 64 bit running Diva 64 bit
Sound Interface: Fireface 400.
Buffer Size: 256 samples.
Input latency shows as 6.82
Output latencys shows as 7.98

We have not done any performance measurements yet. I'm not sure if we even have a Cubase 8 around yet.
Maybe it has new features that do "automatic load balancing" or some such thing - which might interfere with Diva's own multithreading.
It might be interesting to run some tests with other multithreaded VSTi such as Dune2 or Harmor. If Cubase 8 does worse with these too there might be an answer. If not, maybe there's something we could look into.

Hi, I am on Windows 7 64 bit too and I just tested the Cubase 7-8 and with a project I just created using I think 7 instances of Diva.... if anything asio load went down by a very noticeable amount on my system. Cubase 6 was before asio guard I believe....what settings are you using for asio guard?

We have Cubase 8.0.5b2. Is this the version you use for testing or are you using an older beta?
Is DIVA's multi-core button set to ON or OFF (check all instances). How does DIVA perform, when having that button ON for all instances?
And lastly, which revision of DIVA are you using?
Thanks!
Cheers,
Michael

thanks for the quick replies guys. I am using the offical Cubase 8.0 release that came out a couple days ago.
Also yes I always click on multi-threading on Diva at the bottom. Using the latest Diva version 1.31.
I noticed even a single instance of Diva has the Asio meter spiking to 30% in a tiny test project with nothing else inside it. Quite strange. This happens with both Asio guard on and off. seems to make no difference. Its quite striking as it seems Cubase 8 handles my other VSTs so well. I just loaded 50 Jupiter 8V plugins and together they have less Asio usage than 1 Diva. Something is definitely going on!

HI,
I am running VST2 (Urs asked us to not use the VST3 for now if we can) 64 bit and the latest build that we got, build 2709.

Bad news. Seems that VST2 has the same issues for me.
Here's a screenshot of a single instance running the patch HS Civil Surfaces from the default bank: 3 Polysynth.
Check out how high the asio meter hits with nothing but this Diva playing.

sorry in all the diff permutations of testing I forgot to hit multi-core just this once. and yes it makes a huge difference so disregard prior screenshot. thanks
EDIT: ok using VST2 and multicore, DIVA is usable now. Can run 20 instances without spikes. thank you so much

so are you still seeing heavier asio load in c8 vs c6 using vst2?
Like i said on mine I see a marked decrease...
btw, and I don't remember if it was cubase 6 or 7 it was instituted, but you can within cubase save a default patch for each vsti/vst.... so I have one set for diva with multicore enabled, so I always have it enabled for every instance. (I do the same for Bazille, Ace too as well as the gui size I like for each u-he instrument)

i have same issues with diva in cubase 7.5. revision 2709 of diva 1.3.1 with vst2 (not vst3 as per u-he / advice). Crackling happening on simplest project with one diva installed, on most (too many) presets. While average asio load is high enough, the spiking seems to happen on initial key strike, or start of diva calculations? Once the crackling starts it continues apace as if the whole instance is overloaded. pressing the multicore option reduces, but does not (appear to) eliminate the problem.
Accepting diva has a high cpu demand, it can't be right that the simplest project with the minimum diva instances crackles. It makes a great synth completely unusable.
