It's been years I haven't had issues with PC freezing.

Environment

why is it building c++ doesn't use lowest cpu prio? I've been using Visual Studio, and building is a no issue. I've tried to use vscode with c++ and my pc is dying, mouse freezing etc.

@pps83 How are you building? Our C/C++ extension doesn't implement any large scale project building. Are you using CMake Tools to build?

[pps83]

Yes, I think it builds through cmake (perhaps with ninja, not even sure). Would be a good idea to execute these commands with low prio

[sean-mcmanus]

@pps83 Sure, but how exactly is cmake (with ninja) executed? I don't believe our extension is the cause of the issue (the C/C++ extension doesn't directly execute cmake). It might be an issue with CMake Tools if you're using that or with CMake and/or Ninja itself.

[pps83]

I used vscode the same way I do with regular Visual Studio: I use F7 to build, F5 to run etc. Is it cmake tools that does the build command?

[sean-mcmanus]

@pps83 It sounds like you're building with the CMake Tools extension (which adds building via F7) so I'll transfer it there.

FYI, I hit the same issue sometimes when building with CMake Tools so it would be nice to get fixed.

[sean-mcmanus]

@gcampbell-msft I'm not sure if CMake Tools can do anything about this or if CMake and/or Ninja are the cause and/or the OS.

[gcampbell-msft]

@sean-mcmanus and @pps83 It would be great if you could provide the repro that you hit this issue with, so that we could not only attempt to repro, but also to understand if there are specifics about your project that might be handled differently in VS Code that we could investigate to see if there is a performance improvement we could make.

As @sean-mcmanus pointed out, depending on the issue, it could be simply due to CMake or Ninja, but it could also be due to additional things that the CMake Tools extension attempts to do.

Looking forward to getting more info. Thanks!
