Would connecting a laptop to a PC tower increase game performance?
It could actually make your game performance worse, here’s why: When you connect your laptop to another machine, you create a “bottleneck” at the connection point. No network connection type will run as fast as the internal bus on either machine meaning your data can only transfer between the machines as fast as your network connection will allow rather than at the bus speed of the faster machine. Hence, you end up with a data rate that is slowed by your network connection. The best way to increase game performance is one or more of the following upgrades: A faster CPU, more RAM, a better video card (faster chip, more and/or faster video memory), and faster storage (usually HDD) that has faster data access rates.
