How to Fix Lag
Try these first — they're free and solve the problem for most people.
General network tips (not Sudden Attack-specific)
01 Check your real ping to Korean servers
02 Use a wired Ethernet connection instead of WiFi
03 Close background applications eating your bandwidth
04 Disable Windows Auto-Tuning (TCP receive window scaling)
05 Check if your DNS is causing login delays
Still lagging? The problem is likely your ISP's routing to the game servers.
