TLDR: click video and uncheck autoframeskip, apply leatrix latency fix, disable aero theme win vista/7/8
smoothing 0 = possible if you both have the latency fix installed
1 = 10-90ms
make sure you and your opponent have the SAME smoothing setting, otherwise one of u gets smooth gameplay and the other gets choppy shit
Alternative way to disable aero
with the LAN latency fix posted below, you can play even 110 ms at 0-1 smoothing, but if your internet is shit, then your internet is shit.
