Having made great progress using ASIO guard on my new i7 5960 rig, here are the latest stress test results:
Total Plugins: 240
Minimonsta: 80 instances
RND Compressor: 80 instances
Lexicon Concert Hall: 80 instances
Basically, 80 channels of Minimonsta with the RND comp and Lex verb on each channel.
This load causes 100% CPU utilisation 25% of the time (CPU load moves between 82% and 100%)
This should keep me going for a couple of years!
