Neverwinter Nights 2 Hardware Performance Guide
If you're having trouble running Neverwinter Nights 2 at its best, this guide might solve your woes.

Neverwinter Nights 2 will enthrall you with a compelling storyline and addictive gameplay, but trying to enable all the best settings could hinder your gaming experience. Neverwinter Nights 2 is a performance-guzzling monster. Quite a few game settings brought our powerful test system to a screeching halt. If you crank up all the options, you will smother your player and enemy character models in an excessive amount of lighting and shadowing effects. Combat effects and those five torches stuck on the wall add even more performance demands. We had to break out the very best PC components to run the game well, and we still had a tough time keeping frame rates up when we increased the game settings.
We tested Neverwinter Nights 2 using FRAPs and a 25-second demo in the Blacklake district of the city of Neverwinter. We couldn't test in combat situations because fight sequences are very difficult to reproduce, but we believe that the Blacklake district is a fairly challenging area of the game. The game has a built-in V-sync frame rate cap that we couldn't disable. Most frame rates sat below the cap, but we did hit the limit in certain tests. Unlike first-person shooters, where you might need in excess of 60 frames per second for great gameplay, role-playing games like Neverwinter Nights 2 still play very well at a consistent 30 to 40 frames per second.
Neverwinter Nights 2 has quite a few settings you can disable to improve frame rate performance. We tested all the options to find out how much each setting affected frame rate performance.
Most games require powerful video cards, and Neverwinter Nights 2 is no exception. We have performance results for nearly 20 video cards to help you determine how much performance is enough.
Neverwinter Nights 2 loves CPU power. If you give the game more processing power, it'll reward you with better performance. We tested the game up and down the clock-speed ladder on our Intel Core 2 Duo and AMD Athlon 64 X2 CPU-based systems.
A game that feeds on powerful CPUs and video cards usually also likes RAM. We tested Neverwinter Nights 2 with 512MB, 1GB, and 2GB of RAM to see what kind of impact memory has on performance.
Even if you have a powerful system, you might want to disable or lower quite a few settings in Neverwinter Nights 2 to improve performance because some effects just aren't worth the frame rate hit. The settings that deal with shadows in particular affect performance greatly. We managed to improve performance by almost 60 percent when we disabled point light shadows. You can do away with shadows altogether to double frame rates. If adjusting the lighting doesn't completely solve your performance woes, consider decreasing the texture sizes or lowering the resolution to squeeze out a few more frames.
Do not lower any of the texture-filtering settings (texture minification, magnification, and mipmap). Your performance will, in all likelihood, not increase by very much, and the game will get sinfully ugly. We have image comparisons of the texture filtering settings on the next page; however, still images fail to capture how horrible the game looks with reduced filtering.

Texture SettingsLowering texture quality reduces the amount of detail in the image. If you lower texture-filtering settings that deal with minification, magnification, and mipmaps, the game will get ugly. High- and low-texture filtering are a combination of all these settings.

The shadow settings control the number of onscreen objects capable of generating shadows and the type of shadows they create. The shadow map sizes setting determines how detailed the shadows look. Pay particular attention to the shadows cast by the tree leaves.
Turning off point light shadows improves performance considerably, but it also removes much of the shadowing in the game.

We recommend leaving bloom enabled because it adds a lot of life to the game. Draw distances don't seem to affect performance too much, but high settings do improve image quality. Normal maps typically give simple surfaces added depth.

A better video card will help boost performance in Neverwinter Nights 2, but stick with the single-card solutions for now. We had trouble with our SLI and CrossFire dual video card setups. We couldn't get CrossFire mode to work at all, and performance with SLI and the GX2 was less than stellar. We've noticed that games often require a new patch or a graphics-driver revision to play nicely with dual video card configurations.

Most games benefit more from a video card upgrade than a CPU upgrade, but we found that Neverwinter Nights 2 scales well with CPU performance. Note that the game doesn't take advantage of multiple cores--you can get great performance out of a fast single-core chip.

Don't even think about playing the game with 512B of RAM. The 512MB system gave us absolutely atrocious load times, and we experienced some hitching while playing. Load times dropped dramatically once we jumped up to 1GB, but moving up to 2GB didn't seem to provide any huge improvements.
