when playing the beta, no lag noticed at 99% of the time, until I get those rolling skills (demon hunter's roll, and monk's blink strike), then can notice a 0.5~1 second lag between my keypress and character actually rolling.

but overall can really say no lag.

you can always subscribe to various tunneling services to improve the ping a bit when they become available.

diablo 3 is very playable with no noticeable or game breaking lag at 250ms - 300ms.

the in game ping checking "orb" is still green color when the ping is under 300ms.

Have anyone seen d3 content greater than skely king ?

Technical Answer
Port forwarding or port mapping is a technique of translating the address and/or port number of a packet to a new destination possibly accepting such packet(s) in a packet filter (firewall) forwarding the packet according to the routing table. The destination may be a predetermined network port (assuming protocols like TCP and UDP, though the process is not limited to these) on a host within a NAT-masqueraded, typically private network, based on the port number on which it was received at the gateway from the originating host.
The technique is used to permit communications by external hosts with services provided within a private local area network.


Short Answer
If you don't forward the port. Then cannot play smoothly, because some communications packets are blocked by your router or firewall. Windows automatically opens those ports in the firewall when you first run the game, assuming you didn't click block. However on the router side, you need to forward it manually if your router does not support UPnP. But most router do support UPnP. However it is still better to manual port forward as sometimes the UPnP don't really work that well.

in short, if i do port forwarding i can get to lower my latency? yes no?

thanks for answering though

No. But will have more stable connection.

There was a user earlier which didn't forward port and complaint that D3 was lagging for him. I am not sure what he exp is lag or communication error and DC. Most likely his router dont support UPnP so need to manually forward port. After he forwarded the ports can play as normal.

pre-ordered mine from amazon uk. 28pounds, which is Rm140 for a box copy. cant wait for 15th May! =DD

hmm, as for my case, when playing beta, sometimes I do experience some lag when the parties using some skills such as blink, roll, and few other (cant remember the name now). But overall still ok as most of the time I notice the orb is green with ping average around 2xxms - 300ms.Only sometime I notice it change to slightly green-yellow sort of color with latency around 700ms.

Hey guys.
