I think this is an MSBuild setting, but I am running from Visual Studio 2019.
How do I make the VS Output Window less cluttered by removing the 95 lines of Target Performance Summary time details? (I'll enable it when I need to profile the build process - hopefully never.)
You can go to Tools > Options > Projects and Solutions > VC++ Project Setting and check the value of Build Timing. Change it to "No" can remove the Performance Summary at the end of Output window.
If it doesn't work you can go to Tools > Import and Export Settings to Reset all settings.
