Visual Studio 2013 Slow IDE Responsiveness [closed]

Question

For some unknow reason, Visual Studio 2013's IDE seems less responsive. It should be fairly snapping considering that I'm running it on a high end PC with lots of RAM. This happens even when I am not debugging my web application.

When I click on menus, there's a noticable delay before it responds and there's no highlighting of the menu. Clicking on HTML text or items in the solution explorer is also slow. Sometimes there's a pause with the cursor stuck on a text selection state.

Here's my configuration from the Help screen:

Can anything here be the culprit? FYI, I removed the Visual Experience stuff and didn't help.

UPDATE: There's an error message that appears in ActivityLog.xml:

1203 ERROR System.NotImplementedException: The method or operation is not implemented. at Microsoft.VisualStudio.Editor.Implementation.SecondaryVsTextBufferAdapter.Microsoft.VisualStudio.Shell.Interop.IPersistFileFormat.GetCurFile(String& ppszFilename, UInt32& pnFormatIndex) at MadsKristensen.EditorExtensions.IVsExtensions.GetFileName(IPropertyOwner owner) at MadsKristensen.EditorExtensions.Css.UnusedCssTagger.GetTags(NormalizedSnapshotSpanCollection spans) at Microsoft.VisualStudio.Text.Tagging.Implementation.TagAggregator1.<GetTagsForBuffer>d__5.MoveNext() Editor or Editor Extension 2014/04/15 12:35:42.788 1204 ERROR System.NotImplementedException: The method or operation is not implemented. at Microsoft.VisualStudio.Editor.Implementation.SecondaryVsTextBufferAdapter.Microsoft.VisualStudio.Shell.Interop.IPersistFileFormat.GetCurFile(String& ppszFilename, UInt32& pnFormatIndex) at MadsKristensen.EditorExtensions.IVsExtensions.GetFileName(IPropertyOwner owner) at MadsKristensen.EditorExtensions.Css.UnusedCssTagger.GetTags(NormalizedSnapshotSpanCollection spans) at Microsoft.VisualStudio.Text.Tagging.Implementation.TagAggregator1.d__5.MoveNext() Editor or Editor Extension 2014/04/15 12:35:42.940
