This article provides a detailed overview of the nVIDIA ForceWare WHQL Drivers 181.20, specifically designed for Windows Vista operating systems. These drivers are WHQL (Windows Hardware Quality Labs) certified, ensuring a certain level of stability and compatibility. They cater to a wide range of nVIDIA GeForce desktop GPUs, spanning from the 6 series to the 200 series. This comprehensive driver package introduces several key features, performance enhancements, and compatibility improvements aimed at optimizing the user experience for gamers, professionals, and general users alike.
Key Features and Enhancements of nVIDIA ForceWare WHQL Drivers 181.20
The nVIDIA ForceWare WHQL Drivers 181.20 for Windows Vista boast a suite of new features and enhancements, making them a significant upgrade for users of compatible GeForce GPUs.
Expanded GPU Support
A primary highlight is the addition of support for the then-new GeForce GTX 295 and GeForce GTX 285 graphics cards. These high-end GPUs were designed to deliver top-tier performance in gaming and other graphically intensive applications. The driver ensures proper functionality and optimal performance for these cards within the Windows Vista environment.
Enhanced SLI Technology
The 181.20 drivers unlock 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, effectively multiplying graphics performance. This feature enables a significant boost in frame rates and visual fidelity in games and professional applications. The drivers ensure seamless integration and optimal performance when utilizing SLI with compatible GPUs and motherboards.
Dedicated PhysX Acceleration
One of the most notable additions is the full enablement of NVIDIA PhysX acceleration. PhysX is a powerful physics engine that adds realistic and dynamic physical effects to games. With these drivers, users can dedicate a separate GeForce graphics card solely for PhysX processing. This allows the primary GPU to focus on rendering graphics, while the dedicated PhysX card handles complex physics calculations, resulting in more immersive and visually stunning gameplay. It’s important to note that GPU PhysX is supported on all GeForce 8-series, 9-series, and 200-series GPUs with a minimum of 256MB of dedicated graphics memory. The driver package automatically installs PhysX System Software version 8.10.13.
GeForce Plus Power Pack #2
The nVIDIA ForceWare WHQL Drivers 181.20 also support GeForce Plus Power Pack #2. This power pack offers free PhysX and CUDA applications designed to showcase the capabilities of NVIDIA GPUs beyond traditional gaming. These applications could range from interactive demos to utility programs that leverage the parallel processing power of NVIDIA GPUs.
NVIDIA CUDA Video Encoder with H.264 Optimization
The drivers introduce support for the new NVIDIA CUDA Video Encoder, which features H.264 optimization. CUDA (Compute Unified Device Architecture) allows developers to harness the parallel processing power of NVIDIA GPUs for general-purpose computing tasks. The CUDA Video Encoder enables faster and more efficient video encoding, particularly when using the H.264 codec. This is beneficial for video editing, transcoding, and streaming applications.
Performance Improvements
Beyond the new features, the nVIDIA ForceWare WHQL Drivers 181.20 bring significant performance improvements across a range of 3D applications. NVIDIA conducted internal testing, comparing the performance of these drivers against the Release 178 drivers. While the results can vary depending on the specific GPU, system configuration, and game settings, the improvements were substantial.
The original article highlighted specific performance gains in several popular games:
- 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
- Up to 25% performance increase in Devil May Cry 4
- Up to 38% performance increase in Far Cry 2
- Up to 18% performance increase in Race Driver: GRID
- Up to 80% performance increase in Lost Planet: Colonies
