Subject: [PATCH] Further improve server tick loop
|
|
|
|
Improves how the catchup buffer is handled, allowing it to roll both ways
|
|
increasing the effeciency of the thread sleep so it only will sleep once.
|
|
|
|
Also increases the buffer of the catchup to ensure server stays at 20 TPS unless extreme conditions
|
|
|
|
Previous implementation did not calculate TPS correctly.
|
|
Switch to a realistic rolling average and factor in std deviation as an extra reporting variable
|
