Key Improvements and New Features in Version 191.07
The 191.07 driver brought several enhancements to the table, making it a worthwhile upgrade for users with compatible hardware. These improvements span across various areas, including API support, gaming performance, SLI compatibility, and bug fixes.
-
OpenGL 3.2 Support: One of the most notable additions is the support for OpenGL 3.2 for GeForce 8, 9, 100, and 200-series GPUs and ION GPUs. OpenGL is a cross-language, cross-platform API for rendering 2D and 3D vector graphics. This update allows these older GPUs to take advantage of newer OpenGL features, potentially improving performance and visual fidelity in applications and games that utilize this API.
-
Gaming Performance Acceleration: The driver package focused on boosting performance in several popular gaming titles. While the exact performance gains varied depending on the specific GPU, system configuration, and game settings, the reported improvements were significant:
- Up to 12% performance increase in ARMA 2
- Up to 8% performance increase in Batman: Arkham Asylum with GPU PhysX enabled
- Up to 50% performance increase in Call of Juarez: Blood in Bound with SLI enabled
- Up to 14% performance increase in Fallout 3 (indoor scenes) with antialiasing enabled
- Up to 10% performance increase in Far Cry 2 (DX9 version) with antialiasing enabled
- Up to 34% performance increase in Prototype with antialiasing enabled
