Neverwinter Nights 2 Performance Tweaks


[ Via PinoyGamer ]
Running Neverwinter Nights 2 but not getting those framerates you wanted? Neverwinter Nights 2 is a very enjoyable RPG experience along the lines of such classics such as Baldur’s Gate and Planescape but its also has a very complex graphic engine. Here’s what you can do to make Neverwinter Nights 2 run faster on your PC. System Requirements included. Oh one “tweak” to make NWN2 more enjoyable? Crank up those speakers especially during spoken lines between party members. Priceless.
How to make Neverwinter Nights 2 run faster
Please note that this site is not responsible for any tweaks, fixes that may damage your system.

1. Make sure your system specs are ABOVE the minimum requirements listed at the bottom of the page, NWN loads a lot of data so you might want one of those faster hard drives. as always having a faster proccessor and larger memory also helps a lot. My observation is that if your system can handle Bethesda’a Oblivion then you shouldnt have any problems with NWN2.
2. Defrag your system.
3. Install up to date system drivers. This step can fix a lot of your problems.
4. Disable Vsync for NWN2main.exe. This can be done through the Nvidia Panel for Geforce users.
5. Check your game’s graphic settings. Disabling Shadows helps a lot of users. Lowering the resolution can earn you extra framerates, same as disabling Bloom and Water effects. Lower Draw distance also helps espcially with older cards. The advanced Graphic setting tabs has a
couple of editable settings, just pick the lower quality option for faster performance.

Wanna run Neverwinter Nights 2/NWN2 on your puny Intel GMA 950/900 class GPU? =) (As with any tweaks on this page: note that this is not guaranteed to work for every one and may not result in PLAYABLE frame rates, so use it at your own risk)


Link to download “3Danalyze”: Click Here

1. Go to the link posted above
2. Download The 3D Analyzer
3. Extract the files to any directory
4. Open 3DAnalyze.exe
5. Press the big SELECT button
6. Find your nwn2main.exe (I searched for this file and found it in the C Drive in program files. It looks like this: C:\Program Files\Atari\Neverwinter Nights 2\nwn2main.exe)
7. Select it
–>8. Under Directx 8.1 and 9.0 options – > Hardware Limits (cap bits) Check off emulate HW TnL caps
9. Hit run

The solution suggested “emulate pixel shader caps” but did not work for me. HW TnL worked for me. It may be different to some, I have no idea.
I do not know if this works for ALL intel cards but I DO know it works for my GMA 950 or 945.


A Great mind has discovered a way to trick your PC into believing you have a 128mb video card! I have a laptop with a Radeon x300 and thanks to this tip, it now works – I never get the 128mb error!

The developers don’t help us ,so I tried to solve this problem by myself.But for some reason,I could not post topics in Support Forums.So I can only post it Here
Now ,Follow me
Click Star->Run,Type Regedit to enter Registry Editor.The Find HKEY_LOCAL_MACHINE \\ SYSTEM \\ CurrentControlSet \\ Control \\ Video
In this class,you can find some sub class like {C84A0178 – 28C2- 4D98-ACC1 -486446A5E108}or others.
Don’t Worry,Find Binary values named
” HardwareInformation.MemorySize “,Double click it and Mod the Value to 00 00 00 08(Means 128MB Video RAM).Do it like this!
You may find some Values also named ” HardwareInformation.MemorySize “,Edit them all!
Then Type DXDIAG in RUN,you can find your Video RAM changed to 128MB!Then ,Insert the disc,Play them Game!


Possible performace increase for AMD users
If you’re an AMD user. There is an nwnamd.exe file in your install folder. Some AMD users say this helps them out considerably, others report no change.

XFIRE Performance problems
TURN OFF XFIRE. Even though it’s offered as an install with the game, it causes *massive* slow downs with just about everything. Alternatively, you can use the Xfire work around here.

Drive camera fix
Drive camera no longer floats off if you turn around.

Remove intro movies
Rename the .bik files in your movies folder, you’ll see which ones to rename, like wotclogo.bik, etc. This removed all the stupid movies that load when you boot the game.

  1. Thanks so much for posting this, you are my idol. and even more thanks to “The Great Mind” for finding this out. I’ve been trying to run my nwn2 on my new laptop but it fails. the thing is i have 64mb ram i know it’s less than minimum requirements, but i’m searching every corner in the world to find a way for nwn2 to run on it. let’s pray this method works or does anyone have another method? eternally grateful for helpful replies, or email me at

  2. I was hoping if anyboy knew about a way to increase the maximum level cap for NWN2 to whatever you want. Any Ideas?

  3. I need some help. Every time I try getting into a specific District of Neverwinter, it always says, NWN2 has stopped working and closes. It only happens when I attempt to enter that location. I am currently using Windows Vista with a Geforce 8600GT graphic card, Duo Core 2 processor and 2GB ram. Any suggestions?

  4. I’m using a MacBook Pro with great hardware to run just about anything…as of yet.

    I’m using Parallels Desktop to run any Windows programs I have to, including NWN2. At first, I had the “could not find compatible direct3d device…”

    After finding out about the 3dAnalyze, I got rid of that message. Immediately after that problem was fixed, I received the message about the video memory not being 128 MB. After more search (and ending up here) I changed that too to work.

    SO, after the past month of trying to get this going…the NWN2 icon comes up in the task bar, a black box comes up on the screen for about 4 seconds, and then it automatically closes NWN2.

    No notices, no error message, nothing.

    Any suggestions? (Besides buying a couple hundred dollar PC to play a $40 game.)
