Nuendo is rock solid on my very similar machine with 32 & 64 bits.
With most major plugin manufacturers finally having come round to 64bit versions I hardly use the 32 bit version, anymore.
But, as Fredo already mentioned, there are (few) plugins which instantly kill Nuendo and even the OS ( great to have auto safe…). Those are solely 32 bit plugs, here. Once spotted and kicked off the PC it is a pleasure to work on and on …
If you need such a 32 bit plugin the best you can do ist actually to use 32bit Nuendo. For normal operations and nprs there is not too much you are missing. Just the memory restriction is an occasional problem.
What Santa said. I am still swapping between 32bit and 64 bit because I have still a lot of 32 bit plugins.
When using 64 bit Nuendo you have to spend a sunday afternoon checking out which of your 32bit plugins run well with the internal bitbridge and which should better be bridged by jBridge.
For example I have - beside almost everything from Waves, Sonnox, PSP, Voxengo etc - truckloads of freeware stuff - those oldies - for example Digitalfishphones… Blockfish and so on. There are no equivalents for some of those dinosauriers. But they are running 100% solid via jBridge. Even more solid then without - I suffered from denormalisation CPU spikes in the past.
UAD for example will not run with internal bridge - to be precise - it works well, but just to a certain amount of plugins. I had Nuendo Freezes/Quits when opening old projects - till I realized that the crash appeared always at the same moment when loading - when using UAD via jBridge you can blow your cards. Powercore is running fine via internal bridge, Drumagog as well… It is a shame that Drumagog and Powercore are still 32bit. Yea - UAD is 64 bit… but I still have a couple of UAD1…
I was talking about the fact that UAD 1 and 2 Plugins are running great via jBridge, so you can use all DSP of all Cards without problems. Steinberg bridge will make Nuendo/Cubase freeze after 20 plugins or something like that.
As j-bridge is very ceap I wouldn’t hassle with Steinbergs own bridge.
I have used jbridge before on my 32 bit system to access more ram (32 bit Kontakt bridged in 32 bit Nuendo) and now to bridge my remaining 32 bit plugins in 64 bit nuendo and did not have a single problem so far. Performancewise I also can see no difference between a jbridged 32 bit plugin and its 64 bit counterpart…
