I will edit this post to include any tips anyone posts below this so they're all up top. Maybe we can get a sticky for this?
GOG (
http://www.gog.com) - This site sells old games that you can download online. Super handy for buying and installing the all-in-one version of the game with all patches.
Error: CD Key Already In Use - This is a common issue because GOG sells all copies of NWN with the same CD key. So the second person to try to log onto the server with their default GOG serial key will see this message and be blocked. To get your unique key, you need to log into your GOG account
https://www.gog.com/account and select MORE -> SERIAL KEYS.

Performance Issues - These are sadly very common. I thought that my modern machine would chew through NWN1 and make it work like a dream. Not so. Turns out the game is
so old that it doesn't even recognize how certain aspects of how modern machines work. (For example, NWN doesn't really take advantage of multi-core processors because there weren't any at the time!)
Note: Performance issues vary wildly and what works for one person doesn't work for someone else. You kind of just try different things until you find the right combination. I'll try to organize this so that the most-likely fixes to work are up top.
Computer Settings
Run in Compatibility Mode - You can run NWN as though it were on a previous version of windows. This helped me.

1) Right-click the icon you use to launch NWN and select Properties.
2) Select the Compatibility tab.
3) Select the checkbox for Run this program in compatibility for...
4) Select the version of Windows you want to try (Windows XP Service Pack 2 is recommended)
5) Click Apply.
Run as Administrator - Every time I launch the game, I right click the icon and select Run as Administrator.
Set CPU Affinity - This relates to the multi-core issue. You can set NWN to run on just one core of your processor.
open nwnplayer.ini in the main NWN folder. Locate "Client CPU Affinity" and change the value to 1...."
You can experiment with different values for the CPU Affinity depending on how many cores you have. I pulled this quote from a great troubleshooting thread here:

NWN In-Game Settings
- Turn off Shiny Water
- Reduce the number of shadows
[I'll add other suggestions here]
*NOTE: I am NOT an expert on this stuff and at this point the things I tried that more or less worked were a few months ago and I'm fuzzy on them. If you changed a setting recently and noticed an improvement, please post it here.
