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
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.
