i didmt know i thought there was only 4 servers,When i login i dont seem to have the same options as you do i will check again later.Btw whats the turm rate ?ive alway wondered what it does.
Basically, on turnrate 24 you get 24 turns to do something within a second. In the case of turnrate 24 it comes down to one turn per 42ms, as 1000ms divided by 24 is 41.66666ms(rounded up to 42ms).
Latency Low, High and Extra high function as multipliers. The base multiplier is times 1. Low latency is times 2 on top of times 1, in short times 3. Turnrate 24 on Low latency is 125ms/126ms for each turn. High is times 4 at 167/168ms. Extra high is times 5 at 208ms/210ms.
See table for reference:
In short, always test HIGH latency first if the game is lagging even slightly. Don't instantly go for EXTRA HIGH latency because that's just extra ms added per turn.
And as you can see in the table, Turnrate 8 Extra high is three turns per 2 seconds. Koreans consider everything below TR20 LOW to be lagg because micro becomes significantly harder and for some specific forms of micro impossible the lower the turnrate goes and the higher the MS goes.
