“We fixed it,” Mira breathed.
“It’s unplayable,” Mira sighed over Discord. “The relay is throttling UDP packets. My archers freeze mid-draw.” Leo stared at the red dot next to his friend’s name
For three hours, he reverse-engineered the Hamachi client’s network stack using Wireshark. He noticed the pattern: when both clients sent a HB (heartbeat) packet with the same nonce value but different timestamp deltas , the relay server would drop out and try direct UDP again. The problem was that Windows was artificially lowering the virtual adapter’s priority. “It’s unplayable,” Mira sighed over Discord
