Visual Studio 2013/2015 Idle CPU usage

Question

I\'m currently evaluating Visual Studio 2015 RC. I\'ve noticed when running the IDE, The Visual Studio 2015 process is constantly at around 25% CPU usage. Even without a project

Answer 1

In my case, the culprit was Node.js tools for Visual Studio. I had v1.1.2 installed and the cpu was constantly around 25-40%.

A switch to Node.js Tools v1.2 RC resolved the problem completely after an initial high load that went away in a couple of minutes.
