bandwidth limit to 0.5 mbps

Any idea to limit the application google Chrome on Windows?

I live in an area where the Internet is 1Mbps. It is a slow Internet connection to play games online and play on google chrome youtube simultaneously. Youtube video load all possible speed, that causes slowness in the online game. I would like to limit the bandwidth of google chrome to 0.5mps as this runs the online game, and drop velocity when you stop running the online game. I do not know how to start. Any ideas? All the ideas are welcome. Thank you,
