Are you connecting to a computer on your local home network or is it over the internet to another location?
If you are just on your home network, it will work to a degree, but it is really not intended for that purpose. I do not know of any remote software that focuses on game performance specificly.
Any video rendering is done on the remote machine though and just sent as video/pictures to your remote connection. Most performance of a remote connection is based on the network connectivity, hence why I asked if you were staying on your local network or not.
Bottom line, it should work for you, just don't expect great performance.
