GeForce 6 Series - IntelliSample 4.0 and The GeForce 6 GPUs

IntelliSample 4.0 and The GeForce 6 GPUs

Upon launch of the GeForce 7 family of graphics processing units, IntelliSample 4.0 was considered to be an exclusive feature of the GeForce 7 series of GPUs. However, version 91.47 (and subsequent versions) of the Nvidia ForceWare drivers enable the features of IntelliSample 4.0 on the GeForce 6 GPUs. IntelliSample 4.0 introduces two new antialiasing modes, known as Transparency Supersampling Antialiasing and Transparency Multisampling Antialiasing. These new antialiasing modes enhance the image quality of thin-lined objects such as fences, trees, vegetation and grass in various games.

One possible reason for the enabling of IntelliSample 4.0 for GeForce 6 GPUs might be the fact that the GeForce 7100 GS GPUs are based on NV44 chips, the same as the GeForce 6200 models. Because of this, Nvidia had to backport IntelliSample 4.0 features to the NV4x GPUs, and as a result, the entire GeForce 6 family is able to enjoy the benefits of Transparency Antialiasing.

It was already well known across various communities that Transparency Antialiasing could be used on GeForce 6 GPUs by using some third party tweak tools. As of Nvidia ForceWare drivers 175.16, GeForce 6 IntelliSample 4.0 support has been removed.
