Visual Studio 2013/2015 Idle CPU usage

visual-studio-2013visual-studio-2015

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 loaded and without the welcome page it is gobbling up 25% CPU usage at a constant rate. No other applications running other than background services. All other running processes use around an additional 2 to 4 percent CPU overall.

This behavior has also been noticed in Visual Studio 2013.

Is anyone else seeing this behavior? Is this normal? Any suggestions?

Had this same problem. Processor constantly at 45-50% even when the IDE is completely idle.

Turns out the problem is the Microsoft Git Source Code provider.

I turned that off and processor dropped to 0 and the IDE became much more usable.
