It could be that it can vary in multiple areas and depending as well on a lot of different stuff (kernel version, drivers/modules, settings, SW being used, ...). Personally, I always had the feeling that video was slower on Linux (always used nVidia proprietary drivers in Linux), but when I used to play a bit of e-guitar the audio latency was definitely better in Linux (but as well just for audio there are a lot of settings that play some role - e.g. https://wiki.archlinux.org/index.php/Professional_audio https://wiki.archlinux.org/index.php/Professional_audio ).
