It will have no impact as long as no .net program is running. It even have no direct impact if .net programs runs. But sometime it looks like that nVidias OpenGL driver have a problem if a .net programm runs at the same time.
If you are playing OpenGL games you should close .net based programs if you notice a slowdown.
