Why Does StarCraft 2 Lag?

The popularity of StarCraft 2: Wings of Liberty is both a blessing and a curse. As we mentioned, you will compete against other players with differing Internet connection speeds. If you have performance issues when using the Internet in general then you can expect lag spikes when playing StarCraft 2. The two main considerations for lag are your Internet speed and hardware. PC gamers will want to focus on CPU, memory, and graphics card. Everyone needs a fast Internet connection.

Let’s continue to look at the best way to increase your Internet speed and lower ping times. In doing so you can expect less lag and a better gaming experience. We recommend testing a VPN to improve ping and reduce your lag. The key is to find a better route between your system and the game server. Your ISP isn’t focused on this issue as much as VPN providers. They know that it’s a competitive advantage if they can offer you a faster router to key locations. Most of the game developers host regional game servers in the same locations. This allows VPNs to offer better routes and will give you a boost in performance.
