thanks to the last great updates the Cubase Session I'm talking about is now using 50% CPU instead of 75% before. BUT I'cant open more Nebulas! I have 23 Instances of Nebula running, but opening 1-2 more instances = Cubase crashes, even with 50% CPU usage now.
my Reverbs use a Buffer size of 4096 my EQs am Preamp stuff uses a Buffer Size of 1024
with Cuda I can open 5-6 more instances before Cubase crashes.
Some people write they would use 30-50 instances! Are you all using nebula buffer sizes of 8192 ?!?!

Can we get benchmarks of this how Nebula performs? Because normally in all benchmarks difference between an i7-2600 and i7-4770 is about 15% at most in in favour of the 4770, which I don't call 'huge' .

Wow, really? You don't read this as Nebula 3 1.3.712? Pro or Server I get, that is important to ask. But being a bit nitpicky on this now.
But, back to the topic starter: Nebula (or your DAW) really crashing will have nothing to do with your DSPBUFFER or your CPU performance. Most of the time it is RAM related. Although with your 16gb I don't expect that to be a problem as quickly as you describe.
Asking 'how many instances' is way to vague. People using only preamp and console style instances can add a lot more than people using reverbs for instance. An EQ (or any other instance) that has a few knobs will take up more memory than a simple preamp. A reverb with 3.5 second tail will take up way more memory than a preamp of 50ms .
