When using video the screen flashes and performs slowly.
The main cause of this issue is due to the age of your computer. Chances are you're using an older machine with only a single core processor. PerfPRO Studio is very efficient, but when using video, Windows Media Player becomes a very large resource hog. With a dual core processor or more along with using Windows 7 or higher (best scenario) PerfPRO Studio performs extremely well with video. Please read the recommendations at the Download page
when using video.
