Improvements? i didn't noticed anything.
But i noticed that the ping (who were ~ 120 ms before the update) is now around 240 - 300 here (France).
it's now impossible to do some think like drive, fly precisely (Was already hard before) and all the stuff who need precision.
Don't tell me that it's my connection, I have ~22ms on google servers.
sparkdaemon.
EDIT: I use Firestorm, and same problem with Singularity and Alchemy
