multi-tasking while playing game in window mode. For example, While playing skyrim, I'm downloading something from internet, I'm also running a program converting pdf files to mp3, Running antivirus/malwarebytes full scan, I may be converting some more mp4 to mp3 files. I'm also doing making some fancy mp4 videos. Waiting for it to finish. All at the same time, I'm watching funny cat or ridiculous people doing at a gym videos on youtube. All those programs running in the background, Not exactly 60fps on skyrim, but around 40s fps. good enough. It is still playable.
