Jeez are PTRs always so bad in terms of server performance? Ping sitting at the 280-300ms range, frequently spiking to the 400-500s and feeling like you’re playing through water.
I have this issue too, but I’m almost positive its because I’m in Aussie land, and the PTR server is in the US.
My ping is usually about 30ms on local servers if that helps make a comparison for your end.
