--- Comment #8 from Etienne mysteryx93@protonmail.com --- Some more update on the issue. On Windows, sometimes I get 1000-3000ms lag spikes, then the game comes back to normal. On Linux, the lag spikes remain and breaks the game until I quit and rejoin.
Those quick lag spikes on Windows seem to coincide with when the problem starts on Linux.
