Atmel Studio Takes a Very Long Time to Start on My PC but Runs Well in a VM Environment. Is there Something I Can Do With This?

Visual Studio shell (and thus Atmel Studio) uses WPF as a graphics library and does a lot of processing in the GUI thread. WPF has support for hardware acceleration. Some graphics card drivers does not utilize this well and spend time in kernel space even when no graphics update is required. Installing the latest graphics driver may give a performance boost.
