Setting ReceiveThreadPriority=1, ReceiveThreadMethod=1 in ggxxnet.ini helping to reduce pings by 20ms in general. More maxpackets (like 384 or 512) is a good idea too. Need more people to test it.
Yes, 2k,2d is best followup off whiffed SHD, coz everyone knows that u'll try OHK them and probably try to jump and lows will beat their attempts. Also, u can try 5HS to CH or get frame advantege to continue pressure.
