I also experience quite a bit of audio dropouts recently. More than I had before.
I suspect using the Adaptive Limiter (great addition by the way!) and LP EQ is more demanding on the CPU.
But even if I am using only one at a time, I still get more frequent dropouts -in my perception- than before.
I am running on Windows 10, Intel i7 2.6 GHz 16Gb RAM.
If this can be addressed, i'd be more than happy. Because I am impressed what Sonar can do, and extremely happy with it.
