Try raising the DSPBUFFER to 2048, 4096, or 8192 (located in your Nebula's XML file, same folder as the plugin itself). More latency, less CPU.
Also, c'mon 45mins is too long for an answer before you start spamming other threads? Learn some patience buddy
EDIT: I'm sorry, not trying to come off as rude. Have you run other reverbs in Nebula more efficiently? Actually, this may be a problem with the library itself and not Nebula. I don't have GH's libraries unfortunately, so I can't really say.
Do remember that reverbs in general tend to eat up CPU the most (compared to say, compressors). In my experience, this is true in Nebula too.
i asked the question to the acustica support yesterday i wanted to know what gain in performance i would get if i upgraded nebula3 pro to the server edition
here is the answer from Acustica :
it will depends on a lot of factors. Nebula3 Server is CORE6 ready and will be also CORE7 ready. Nebula3 Server has RAM sharing feature and you will save RAM but not CPU if you don't have Intel i7/i5 generation 4/5. CORE7 will add new CPU optimizations for lasted Intel's CPUs
i dont seeing that this depends on a lot of factors, the only factor i see is what cpu you have
since i got a mac mini late 2012 i7 ivy bridge 3rd generation it seems there is not mush to gain from upgrading actually, i have still not had a ram problem and core 7 will not gain any power optimisation either sadly as explained you have to have latest intel cpu`s to gain something from core7
is a little disappointing news that an almost 3 years old computer which im not considering as very old already is outdated for core7(and even core 6 when it comes to nebula) but what to do, i cant move away from my LPX so i have to stick to my mac
i really dont hope this apply to the aquas to but i have a suspicion it does im gonna ask them the same question on the aquas to
i really dont have the funds to buy a new mac every two years hehe And Apple really wrecked the latest mac minis with not offering an quad on they're latest Mac mini line, what a shame
the problem with mac always is and was that they are too expensive in comparison to the power you get from a windowsn pc with the same money. Also upgrades in a normal windows computer are many times easier and cheaper. I recently bought a i7 4890k with 4.000 Mhz and a new mainboard and my new computer was finished.
Go and get rid of mac in the next months and try to get a workstation computer... Of course there is a hype around mac and it is said they would sound better with music... but that is of course bullshit:) Some years ago i wanted also a mac mini but i figured out that it makes no sence to pay so much money for crap...
Windows 10 is so good OS... there is no reason for OSx in my point of view.
Of course all mac user now will cry and they will stone me

i agree on macs being to expensive but thats not the point.
a lot of people dont know it seems that you must have a 4/5 gen cpu to take advantage of nebula 3 server core6 and core7 so many buy the server in good faith that they can run mush more nebulas on it compared to neb3 pro and personally i cant move away from Logic Pro X. that is my preferred daw i have tried most daws out there but i always go back to LPX
i have nothing against pc`s as i own a couple of them and im very aware of pc`s is just as good a music computer a wave file is a wave file or whatever format the daw use
maby its cheap for you going out and upgrade your computer , but some with an older pc quad that is still powerful with for example sandy bridge or ivy bridge have to change their main board , ram, and cpu , thats not super cheap , not if you're going for some of the fastest cpu`s
i plan to build my self a powerful hackintosh at a later time when i got the cash
im not blaming Acustica for using 4/5 gen cpu`s for core6 and 7 im sure there is a very good reason for it
i just dont know why this is not common knowledge it should be very clear in the description when you buy for example neb server that you need at least a 4/5 gen cpu to take full advantage of core 6 and the upcoming core 7 , thats my point
