What is vvis.exe and why does it take up 99% of my CPU???

[Mama Snail]

So my computer's been really sluggish lately so I went into my task manager to see what tasks I could close, then went into the resource monitor. Turns out, there's an executable in the GarrysMod/bin folder called vvis that was taking up 99% of my CPU!

What is the purpose of this file, why does it take up so much cpu, and WHY doesn't the process automatically end when the game closes? Most importantly, can the game be run without it?

That vvis.exe should be appear running when the map is compiling in Hammer map editor.
Did you close Hammer map editor while compile/vvis.exe is running?

The map should already be compiled so I don't know why it's still open.

Do I need to have it running when I'm playing a map I made? If the map isn't compiled then how do I compile it?

I think I figured out the problem. At one point I had to force quit Hammer.
