superfly2000: - I would get and install the 1.69 patch (or critical rebuild as it is called sometimes) anyway. I mean at least it wont break anything...I'd do it just to be sure.
- Check the "Client CPU Affinity" setting in the nwnplayer.ini file. NWN doesn't support multiple processors. You have to set NWN's affinity so that it only runs on a single core. In the ini file set "Client CPU Affinity=1". If the line does not exist you can add it.
- Are you by chance running a newer Nvidia card? Say 200 series and up? If so grab the latest 280.xx drivers. That solved lag issues for a lot of folks.
- Not sure about this but if nothing else works you could also try getting an older Direct X version (9b I think it was).
The 1.69 crit rebuild is a pointless download for gog users. A reinstall would do the same thing and nothing to download.
The "Client CPU Affinity" fix is only relevant to vista OS. Win7 sorts it out for you,
Superfly is right about drivers tho. The right video and sound drivers are vital. Also, check out
Installation guide. Normally something wrong with the install would stop the gane running completely, but no harm in checklisting the install is correct. It is probably drivers tho. NWN needs openGL ability and the directX superfly mentioned
Good luck :)
