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?

When the processor is idle, it has a high System Idle Process in the CPU column, often between 70 and 90. If you are not currently using or running any programs, a high idle percent is normal.
These Windows processes are designed to use very little of your processing power or memory under ordinary circumstances — you'll often see them using 0% or 1% in Task Manager. When your PC is idle, all of these processes together will usually use less than 10% of your CPU capacity.
I have recently downloaded Visual Studio 2022 and have found it using a high amount of CPU and memory. This causes Visual Studio (as well as my computer) to slow down at times. The CPU usage fluctuates between 20% - 99% and the Memory usage fluctuates between 2GB - 14GB of memory.
Requires 1 GB of RAM (1.5 GB if running on a virtual machine) Requires 1 GB of available hard disk space. Requires 1024 by 768 or higher display resolution.
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.

In my case disabling Telerik ASP.NET MVC Extension solved high CPU issue.
High CPU load started on solution load and didn't drop (40% with one, 80% with two solutions) until VS was closed or even sometimes after (had to kill the process).
Tools->Extensions and Updates->Installed, find the extension and click 'Disable'.
