Seems to be pretty consistent atm:
--- linux.co.uk ping statistics --- 10 packets transmitted, 10 received, 0% packet loss, time 9015ms rtt min/avg/max/mdev = 54.942/56.202/57.407/0.808 ms
I’ll be honest, on the PS3 playing GT5 online I’ve never seen any major lag or lag at all tbh. Usually really smooth.
