I have Sonar on three computers. My desktop which is very complex, a tablet and a laptop. Sonar Platinum runs on all three quite well. It is stable on all of them. Further the tablet and laptop use the internal sound chip. Their specs are on the low end. The tablet is a Atom with 4 cores. The laptop has a 2 core processor. Both have only 2 GB of memory.
All run Windows 10 pro. The tablet is touch enabled. It also uses wifi and bluetooth. So does the laptop.
What is it that makes me able to run Sonar without issues? I haven't the faintest idea. I suspect all of my computers are good quality and that contributes to stability. I wish I could fix everyones problems but I can't. This thread is really about the stability of Sonar 2015. It seems that posting in this thread how unstable your Sonar is is off topic.
I would hope those that are having unstable Sonar problems start their own thread about it that this forum can help fix. I don't see posting here as being productive. Also it will create conflict.
BTW X3 was very stable too.
