Here are my thoughts as no-one else has chimed in and these are just my experiences. I don't think that speed or bandwith has been an issue even with version 2.IMHO other issues come first for sure. For example I could never really get a second instance to play nice.That goes with any cuda plug I have tried. That goes for the reverb by Liquidsonics - does the same thing. Get crackling and my whole DAW glitches and grinds to a halt with a second instance. Maybe settings on my side here but it proved to be less reliable than native power. So I built another computer server and have never been happier. Great to feel my DAW so responsive and the number crunching happening on my other comp. I also have a workflow that allows realtime performance in a thread here that requires turning the kernels to clean for mixing - full for render. You may consider that although the promise is there cuda may not be what you hope for. Opencl has some promise but I am sure I read that Acustica may not be going that way.
