- GeForce 8 Series: (e.g., GeForce 8600, 8800)
- GeForce 9 Series: (e.g., GeForce 9600, 9800)
- GeForce 200 Series: (e.g., GeForce GT 220, GTS 250, GTX 260, GTX 280)
It is crucial to verify that your graphics card belongs to one of these series before installing the drivers. Installing the wrong drivers can lead to system instability or non-functionality of the GPU.
New and Enhanced Features
The nVIDIA ForceWare WHQL Drivers 181.20 introduce several notable features and improvements:
-
GeForce GTX 295 and GTX 285 Support: A key addition is the full support for the then-new GeForce GTX 295 and GeForce GTX 285 graphics cards. This ensures optimal performance and stability for users with these high-end GPUs.
-
SLI Technology on Intel X58 Motherboards: The drivers enable 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. This feature is particularly beneficial for gamers and users who require high frame rates and smooth visuals in demanding applications. All SLI-certified GPUs are compatible.
-
Dedicated GPU PhysX Acceleration: A significant advancement is the support for NVIDIA PhysX acceleration on a dedicated GeForce graphics card. PhysX is a physics engine that enhances the realism of games by simulating complex physical interactions, such as cloth movement, particle effects, and fluid dynamics. By dedicating a separate GeForce card for PhysX processing, users can offload the physics calculations from the primary GPU, resulting in improved overall performance and more immersive gaming experiences. GPU PhysX is supported on all GeForce 8-series, 9-series and 200-series GPUs with a minimum of 256MB dedicated graphics memory. The driver package automatically installs PhysX System Software version 8.10.13.
-
GeForce Plus Power Pack #2 Support: The drivers support GeForce Plus Power Pack #2, a collection of free PhysX and CUDA applications designed to showcase the capabilities of NVIDIA GPUs.
-
NVIDIA CUDA Video Encoder with H.264 Optimization: The nVIDIA ForceWare WHQL Drivers 181.20 add support for the new NVIDIA CUDA Video Encoder with H.264 optimization. CUDA (Compute Unified Device Architecture) is a parallel computing platform that allows developers to leverage the processing power of NVIDIA GPUs for a wide range of applications, including video encoding. The CUDA Video Encoder provides hardware acceleration for H.264 video encoding, resulting in faster encoding times and improved video quality.
