Multiplayer movement lag

[Legacy_SirKerrald]

               Hey folks. I bought Diamond for a friend so we could play the expansions (we rocked the original campaign awhile back and had no issues). Well the problem we're hitting is that he is getting some funky movement lag issues on multiplayer but not single player. We tried trouble shooting it and what we've deduced so far is that it isn't my server that is lagging (another person was connected without issue), his internet is fine (speed test came back fine), he can run single player without movement lag, but when he posts his own server, with no one connected he still has the glitchy laggy warpy movement. So it seems to definitely be his client and only when playing multiplayer, hosting or otherwise. Anyone have any ideas?

               Basics.  

Processor affinity is set correctly.  Check nwnplayer.ini for the line about ClientCPUAffinity = 0 or something above 0?



He is running nwn as administrator and in xp sp3 compatibility mode?



What OS are you running the game on?

               I know he has XP as his operating system, its an older laptop but I'm pretty sure that windows is up to date so it would be sp3. Not sure on processor affinity. Like I said, it runs perfectly in singleplayer, its only multiplayer that he's having this issue with. Would the affinity settings still play into it at that point? It seems like it should either be a networking issue (although the problem persists when he is hosting and no one is on the server), or a network coding issue.

               I have seen this resolved by changing affinity sooooo  '>

               Yeah unfortunately that did not resolve it. Set his affinity to -1. '>

               well if its only multiplayer I'd check if my Firewall and Anti virus have exceptions for nwmain.exe and nwserver.exe, and if Port 5120 (default) is open in the firewall. He can change the Port in nwnplayer.ini (Client Port)
