Hello Ed,
Sorry for the delay. I do hope to make some quick before-vs.-after performance benchmarks on my Windows 10 and macOS 10.13 installations in the next day or two, but I've been waiting for my virus scanner software (McAfee) to produce an update that allows the necessary Windows patch to install.
Unfortunately there almost certainly isn't anything useful we could actually do anyway, beyond giving a broad indication of what performance degradation (in terms of polyphony, resilience to audio glitches, and organ loading times) the OS patches cause on my own particular computer installations. If the OS patches cause the whole CPU cache to be flushed regularly then my guess is that the performance impacts could be very significant for any CPU/latency/memory-intensive software, potentially including Hauptwerk and probably most other professional real-time audio/MIDI software, but I don't know for certain yet. (CPU cache does massively affect Hauptwerk's real-time performance/polyphony in general.)
My understanding is that the issue could only truly be addressed by a future generation of CPUs, so probably for now the only realistic options are either to put up with any performance degradation from the OS patches, or to keep the computer permanently disconnected from the Internet from now on, and avoid applying them. Neither is ideal!
Best regards, Martin.
