Playing fast moving games over an internet connection poses a number of technical challenges, including latency - the time the remote system takes to execute a command.
This is particularly true in multicore systems because cores actually can be sized differently, using more or less power as needed for a specific function and sometimes using multiple cores to execute the same command.
More often than not, however, we had to keep lifting and repositioning the Vu over the tag to get it to properly recognize the command we were trying to execute.
