When I run WoW without HB, latency(local and global) is very small (green)
But when I run WoW with HB - latency(local) is high (red), global latency remains normal.
Because of this problem slows farming. How can I fix this?
Also, the WoWclient will tell you the exact numbers for the 'latency' if you hover over the 'computer' icon in the WoWclient. Please tell us what these numbers are for each case.
