I recently received a new laptop at work – a 2.4Ghz i7 with 16 Gb of memory.
That’s quite a beast of a laptop, so you’d think it would have no problem coping with Visual Studio 2013. But over the last few days it’s been frustrating me a little – there’s a noticeable lag when typing, and Visual Studio as well as various other programs were performing a little slow.
I immediately disabled all extensions, and removed the recently installed virus checker, but to no avail.
It wasn’t until I checked Task Manager that I noticed the problem, CPU usage was 0% of 0.77 Ghz.
That can’t be right!
It turns out I had switched the power profile last week while running on battery, and changed to “Power Saver” mode. I thought these settings only took effect when running on battery? Apparently not. I’m now back on “High Performance”, and Visual Studio is once again responsive.
