We use both Macs and PCs in our large television productions. It’s been my experience that Nuendo is badly optimized for multicore. Pull up Activity Monitor with the CPU window showing all cores - on our 4 core systems with HT the eight virtual cores are badly utilized with only the odd numbered cores actually getting much use. Core 1 is utilized more than any others by a substantial amount. Our 6 core and 12 core systems are even worse.
I’m well familiar with the multicore issues and scaling but it’s simple to see in OSX it’s not done well. I know it CAN be done better as there are some other near-real-time applications under OSX that do it well. There are differences between Windows and OSX but Nuendo performance in OSX is not as good as it could be compared to Nuendo performance in Windows.
This is separate from the low-latency discussions where the difference becomes even worse - CoreAudio has issues with very low latencies.
We’‘ve used Nuendo ever since it came out for the Mac and I appreciate it very much, it’s generated us much income and satisfaction in a job done well. Therefore my criticism is about improvement. It’s my opinion that the optimizations necessary for any dsp app in any OS are better done for Windows than in OSX. It’s been the complaint among Mac users for many years that Nuendo is “PC-centric”, whatever that really means, and while I don’t tend to use vague terms it sort of describes the underlying dsp optimizations done for Windows that are not as familiar to Steinberg under OSX. OSX may not meet Windows’ performance, but it’s better than Nuendo currently indicates.
My opinions after many years using everything,
