Summary: Get a really good computer for ProPresenter. A dual core laptop with integrated graphics does NOT work very well with ProPresenter 5 / 6 Windows. Whilst the Mac version is proven but not perfect, the Windows version is generally “slow” as my volunteers tell me. Test things out before going live!! Editorial note: If you’re thinking about buying ProPresenter 6 Windows, I recommend you take a look at the official forums beforehand to get a feel for the kind of problems others have/are facing with the software.
