Very fast internet connection. no packet loss, low ping. Still losing on time due to slow server.

Why is it that if i make a move with 0.5s left on the clock, the game is regularly stopped and it states that i timed out? Half a second is half a second. So many winning games where the server is too slow to process the client input... It seems like the only option for bullet chess is currently Lichess.

The time it takes your move to get from your client to the the server is apparently higher than the time left on the official server clock after accounting for allowed lag.

There are some things you can do to minimize issues, but it's possible something between you and the servers are causing more lag than is allowed.

Thanks for the reply. I've done the above. ping averages under 10 ms & everything is reset and configured correctly. Perhaps it's chrome. I also notice consistent 2 second freezes during the start of games. In puzzle battle, there are no freezes, but my opponent will have solved the first puzzle before i'm allowed to move the pieces.
