Ok Guys I have Massive Lag since the last Patch, it takes 5Second to kill a Monster! I thought it was my internet but it isnt

What I already Tried

1) Reinstall Maplestory

2) Router Reset

3) Wlan Driver Update

4) Firewall + Antivirus deactivate

Strangely it happend since the last Patch , before the patch everything was fine
