How fast does your computer have to be to play league of legends

Surprisingly low system requirements are needed. I am running it on lowest specs on a bootcamped mini mac with less than a gig of ram. To run most comfortably I would suggest atleast 2 gig of ram. Most graphics card within the last 5 years should be able to run it. There is nothing stopping you from trying it though since its a free download. Hope this helps.
