Nvidia Control Panel Setting

I was having a word with my Pal Steve last night, and we got on to the subject of graphic card settings, as he'd just updated his drivers.
So I decided like the windows install tutorial, why not do a Nvidia control panel guide.
Soz it's a bit long again, but I thought it might help shed some light on a few of the settings and what they mean and how to squeeze that extra fps from the old trusty graphics card

Firstly make sure you have the latest ver. of the drivers. Drivers - Download NVIDIA Drivers

Some of the setting names and the order in which they're listed may differ slightly beween XP and Vista, and also depending on the specific driver version and model of graphics card you're using. Furthermore some settings below may not exist in certain versions of the Forceware drivers, as they may be very new, or very old, or available only to specific models of graphics cards, and hence not visible in your Forceware Control Panel.

Make sure you are in Advanced View (check under the View menu). By default the settings changed under here apply to all games and 3D applications, hence the name 'Global Settings'. To use specific settings for individual games, see the 'Program Settings' tab. Most settings are covered below:



Anisotropic filtering (AF): This is a feature of some video cards that sharpens the details of the fading-away part of a 3D object that recedes into the distance



In computer graphics, antialiasing is a technique for diminishing jaggies - stairstep-like lines that should be smooth. Jaggies occur because the screen display doesn't have a high enough resolution to represent a smooth line.
If you are unsure of how to configure antialiasing, use the "Application controlled" option. Your display will automatically adjust to the application's specification.



Gamma correct antialiasing: This essentially provides superior colour reproduction. It can improve your subjective opinion of the image. It can have noticeable effect on thin surfaces such as power lines often found in games like Half Life 2 or Call of Duty



Ambient Occlusion: This setting can be used to force Ambient Occlusion in certain games. By enabling this option and at progressively higher settings, the realism of lighting is enhanced in the way ambient light generates shadows - there is greater depth and richer shadowing in the scene. However this setting can also significantly reduce FPS, at times crippling frame rates. It is generally recommended that this option be set to Off globally, and if you wish to experiment with it, only enable it in specific game profiles which support it.



Antialiasing Mode: This allows you to control how NVIDIA antialiasing is applied in your 3D applications. This feature is available only with GeForce 8 Series and later GPUs.

Antialiasing Setting: This setting allows you to set the antialiasing level to use in your 3D applications. You can choose either to let the application determine the antialiasing settings, turn antialiasing completely off, or select from 2x, 4x, 8x, 16x (This depends on your card model)
This item is greyed out if Application-controlled or Off was selected under Antialiasing - Mode.

Antialiasing Transparency: This allows you to minimise the visible aliasing on the edges of images with transparent textures. Multisampling provides superior performance. Supersampling provides superior quality.
In simple terms, multisampling only cleans the edges of the polygons that make up the scene.
Supersampling, on the other hand, renders the scene at a considerably higher resolution and then down-samples pixel samples to the required resolution. This costs a lot of performance and isn't practical in most scenarios.



Conformant Texture Clamp: This refers to a method the Forceware drivers use to determine the way texture boundaries appear, but only in OpenGL games. Initially set Conformant Texture Clamping to 'Use Hardware' for optimal visual quality and performance. Then if in a particular OpenGL game you notice laggy behavior or strange lines in textures for example you can set this option to 'Use OpenGL Specification' to see if things improve. If this is still not the case, then finally set this to Off.

Error Reporting: By turning off the checking of error reporting, particularly in OpenGL games, you will get increased performance, so this should be left at its default of Off.

Maximum Pre-Rendered Frames: The default value is 3 - higher values tend to result in smoother but more laggy gameplay, while lower values can help reduce mouse and keyboard lag. However extremely low values such as 0 may hurt performance, so I recommend this option be kept at its default of 3 globally. Remember, in most cases mouse lag is due to low framerates, so adjusting this option is not an automatic cure to lag issues, nor should it be the first thing you try.

Multi-display/Mixed-GPU Acceleration: Only change this if you have more than one screen

Power Management Mode: Available only for the GeForce 9 series and above. Adaptive is the recommended setting. However if you are concerned that a game is not performing properly, particularly for troubleshooting purposes, then you can change this setting to 'Prefer Maximum Performance' to ensure that the card is always running at maximum clock speed.

SLI Performance Mode: If you have more than one card running in SLI then leave this setting on Nvidia recommended.

Texture Filtering Anisotropic Sample Optimization: If set to On, it uses an optimized texture sampling technique resulting in a slight drop in image quality in return for faster performance. Set it On for best performance.

Texture Filtering Negative LOD Bias: This is the Level of Detail, and in some games you can alter the LOD Bias to sharpen details on screen. In such cases, you should set this setting to Allow, however note that altering LOD Bias can introduce aliasing (jaggedness to lines and edges) and shimmering. You can set negative LOD bias to clamp. It doesn't hurt performance, and if the game doesn't use negative LOD bias, the setting has no effect.

Texture Filtering Quality: This setting determines among other things the level of Anisotropic and Trilinear texture filtering optimizations applied by the Forceware drivers. Generally speaking, the High Performance setting enables all optimizations, meaning slightly lower image quality but the highest level of performance. If you select Performance, some optimizations will be disabled, progressively more if you choose Quality. For most people the improvement in image quality is not substantial enough to warrant setting this too high.



Texture Filtering Trilinear Optimization: Enabling Trilinear Optimization will result in better performance, but can reduce the quality of textures slightly. In general it is recommended that you enable Trilinear Optimization.

Triple buffering: Set this to On. Most modern cards now have 3 buffers and the graphics hardware can start rendering into the 3rd buffer without having to wait for the front buffer. Let's just say it helps maintaining frame rate when Vertical Synchronization (VSync) is enabled in games.



Vertical Sync: VSync is the synchronization of your monitor and graphics card's abilities to draw a certain number of frames per second (or FPS) on the screen. If Vertical Sync is disabled, your FPS will improve, and it can now also exceed the refresh rate cap, however you may notice some screen "tearing" In general it is strongly recommended that Vertical sync be disabled in all games to improve performance. Since almost every current game has the option to enable or disable VSync in the in-game settings.



Well I hope this helps a bit. Some of this tutorial is sourced from different sights, and I've just reworded allot of it to make it more user friendly. This one only covers Nvidia cards, but I'll do a ATI ver when I get some more time.

If you have any questions or comments, just give us a shout and I'll see what we can do
