NVIDIA ForceWare WHQL Drivers 181.20 for Windows Vista 64-bit

This article provides comprehensive information regarding the NVIDIA ForceWare WHQL Drivers 181.20, specifically designed for 64-bit versions of Windows Vista. These drivers are WHQL (Windows Hardware Quality Labs) certified, ensuring stability and compatibility with a range of NVIDIA GeForce GPUs. The 181.20 release targeted users with GeForce 6, 7, 8, 9, and 200-series desktop graphics cards, offering a variety of improvements, new features, and bug fixes.

Compatibility and Supported Hardware

The NVIDIA ForceWare WHQL Drivers 181.20 support a wide spectrum of NVIDIA’s desktop GPUs, catering to both mainstream and high-end users of the time. Officially, the driver package is designed for the following series:

• GeForce 6 Series: Covering a broad range of cards released during that generation.
• GeForce 7 Series: Another generation of NVIDIA cards aimed at improving performance and features over its predecessor.
• GeForce 8 Series: Introducing a new architecture, these cards were popular for their performance and features.
• GeForce 9 Series: Refining the 8-series architecture for enhanced efficiency and performance.
• GeForce 200 Series: Representing the higher-end offerings from NVIDIA, including the newly supported GeForce GTX 295 and GeForce GTX 285.

Key New Features and Enhancements

The 181.20 driver package introduced several notable features and enhancements:

• GeForce GTX 295 and GTX 285 Support: A primary highlight of this release was the official driver support for the GeForce GTX 295 and GeForce GTX 285 graphics cards. These were high-performance cards at the time, and this driver ensured optimal operation and stability.
• SLI Technology on Intel X58 Motherboards: The driver enabled NVIDIA SLI (Scalable Link Interface) technology on SLI-certified Intel X58-based motherboards. SLI allows users to combine the processing power of multiple NVIDIA GPUs for increased graphics performance, particularly beneficial in demanding games and applications. This feature was compatible with all SLI-certified GPUs.
• Dedicated PhysX Acceleration: A significant feature was the enabling of NVIDIA PhysX acceleration using a dedicated GeForce graphics card. PhysX is a physics engine that adds realistic environmental interactions and effects to games. By dedicating a separate GPU to PhysX processing, users could offload this workload from the primary graphics card, resulting in smoother gameplay and more detailed visual effects. GPU PhysX was supported on all GeForce 8, 9, and 200-series GPUs with a minimum of 256MB of dedicated graphics memory. The driver package automatically installed PhysX System Software version 8.10.13.
• GeForce Plus Power Pack #2 Support: The drivers supported GeForce Plus Power Pack #2, which provided users with free PhysX and CUDA applications. These applications demonstrated the capabilities of NVIDIA’s hardware and software ecosystem.
• NVIDIA CUDA Video Encoder with H.264 Optimization: Added support for the new NVIDIA CUDA Video Encoder with H.264 optimization, accelerating video encoding tasks using NVIDIA’s CUDA architecture.

Performance Improvements

The NVIDIA ForceWare WHQL Drivers 181.20 aimed to deliver substantial performance improvements across various 3D applications. NVIDIA provided comparative data against the Release 178 drivers, noting that actual results would vary depending on the GPU, system configuration, and game settings. Some of the reported improvements included:

• Up to 10% performance increase in 3DMark Vantage (performance preset)
• Up to 13% performance increase in Assassin’s Creed
• Up to 13% performance increase in BioShock
• Up to 15% performance increase in Company of Heroes: Opposing Fronts
• Up to 10% performance increase in Crysis Warhead
