  • CineFX 4.0

    The fourth-generation NVIDIA® CineFX® engine builds unimaginable speed into the NVIDIA® GeForce® graphics processing units (GPUs). Using the CineFX 4.0 engine, developers can create and display the most advanced and high-quality visual effects for emerging PC games and other cutting-edge visual applications.

  • Intellisample 4.0

    The fourth-generation Intellisample technology introduces two new antialiasing modes—transparency adaptive supersampling and transparency adaptive multisampling—which increase the quality and performance of antialiasing.

  • UltraShadow II Technology

    Enhances the performance of bleeding-edge games, featuring complex scenes with multiple light sources and objects. 2nd-generation technology delivers more than 4x the shadow processing power over the previous generation.
