Thank you so much for this post.
I never had Cubase crashing on me. However, I was fighting ASIO Spikes into the red and occasional crackles for years.
I added the registry entry as suggested onto my Cubase8 Folder, and the ASIO Spikes are - gone! I observe this improvement on my Cubase 8.0.20 Workstation, as well as, on my Cubase 7.5 machine.
I am happy.
regards, and thank you!
