This article provides information regarding the Nvidia OpenGL 3.0 Beta Driver for Windows XP/Vista 64-bit, a release targeted towards developers eager to explore the capabilities of the new OpenGL 3.0 and GLSL 1.30 specifications. This driver, while a beta, offers a glimpse into the future of graphics programming and allows developers to begin adapting their codebases to leverage the latest features.
Intended Audience and Purpose
The primary audience for this Nvidia OpenGL 3.0 Beta Driver for Windows XP/Vista 64-bit is software developers working with OpenGL. It is designed to provide an early access pathway to the new functionalities offered by OpenGL 3.0 and its associated shading language, GLSL 1.30. This allows developers to experiment, prototype, and prepare for the eventual widespread adoption of these standards.
It’s important to note that the features offered by this driver are not enabled by default. Developers need to utilize the nvemulate utility, as detailed on the NVIDIA Developer website (https://developer.nvidia.com/object/nvemulate.html), to activate the OpenGL 3.0 functionality. This utility allows for controlled experimentation and ensures that existing OpenGL 2.1 applications remain unaffected. On Linux platforms, enabling OpenGL 3.0 functionality does not require any special steps.
Hardware Compatibility
The Nvidia OpenGL 3.0 Beta Driver for Windows XP/Vista 64-bit is specifically designed to work with certain NVIDIA graphics cards that possess the necessary hardware capabilities. These cards generally belong to the G80 architecture or newer. The following lists detail the compatible desktop and notebook GPUs:
Desktop:
- Quadro FX 370, 570, 1700, 3700, 4600, 4700×2, 5600
- GeForce 8000 series or higher (including the GeForce GTX 260 and 280)
Notebook:
- Quadro FX 360M, 370M, 570M, 770M, 1600M, 1700M, 2700M, 3600M, 3700M
- GeForce 8000 series or higher
Users with older NVIDIA GPUs (NV3x, NV4x, or G7x) will not be able to utilize the OpenGL 3.0 features provided by this driver.
Supported and Unsupported Features
This beta driver aims to implement the full OpenGL 3.0 and GLSL 1.30 specifications, with a few exceptions. The following features are not supported in this release:
- One-channel (RED) and two-channel (RG) textures
- The Clearbuffer API
- Windowless rendering support (NVIDIA suggests using GPU affinity as an alternative)
- Forward-compatible context
- Debug Context
Despite these limitations, the driver does expose several new extensions, including:
OpenGL 2.1 extensions:
- ARB_vertex_array_object
- ARB_framebuffer_object
- ARB_half_float_vertex
OpenGL 3.0 extensions:
- WGL_create_context
- GLX_create_context
- ARB_draw_instanced
- ARB_geometry_shader4
- ARB_texture_buffer_object
Improvements Over Previous Beta (177.89)
This Nvidia OpenGL 3.0 Beta Driver for Windows XP/Vista 64-bit release incorporates several improvements and bug fixes compared to the previous 177.89 beta driver. These include:
- Linux Support: Identical OpenGL 3.0 and GLSL 1.30 functionality support between the Linux and Windows releases.
- Mixed-Size FBO Attachments: The driver now allows rendering to a Framebuffer Object (FBO) with mixed-size attachments.
- VAO Enhancements: Bug fixes and performance improvements related to Vertex Array Objects (VAOs).
- EXT_texture_swizzle Support: Implementation of the EXT_texture_swizzle extension.
- Transform Feedback Completion: Missing functionality for transform feedback has been implemented.
- General Bug Fixes: Various other bug fixes have been incorporated.

OpenGL 3.0 on NVIDIA Hardware: Frequently Asked Questions
The following are answers to frequently asked questions concerning OpenGL 3.0 support on NVIDIA hardware:
1) How do I start using OpenGL 3.0 in my code base?
To utilize OpenGL 3.0 and later versions, applications must explicitly opt-in. This requires using the CreateContextAttribsARB function (defined in the WGL/GLX_ARB_create_context extensions) to request a context that supports OpenGL 3.0 or later. Using existing WGL/GLX context creation calls will result in an OpenGL 2.1 context. This ensures that existing applications continue to function as expected.
2) What about deprecation and removing functionality from OpenGL?
OpenGL 3.0 introduced a deprecation and profile mechanism. Deprecation signifies that a feature is marked for removal in a future version of the OpenGL specification. While not removed in OpenGL 3.0 itself, future versions may eliminate certain features. The OpenGL ARB provides a mechanism (profile or ARB-approved extension) for encapsulating functionality for specific markets.
More information on new features, deprecation, and profiles can be found in the NVISION08 presentations:
- OpenGL & the Future
- OpenGL on NVIDIA
Slide 23 of the latter presentation provides an overview of extensions incorporated into core OpenGL 3.0.
3) Will existing applications still work on current and future shipping hardware?
NVIDIA has no plans to drop support for OpenGL 2.1 and earlier versions on current and future hardware. Existing applications will continue to function.
4) What NVIDIA hardware supports OpenGL 3.0?
OpenGL 3.0 requires G80 or newer hardware and is not supported on NV3x, NV4x, or G7x GPUs. Compatible GPUs are listed above under "Hardware Compatibility."
5) (Missing from original – Intentionally left out)
6) Is NVIDIA going to remove functionality from OpenGL in the future?
NVIDIA aims to avoid removing features relied upon by ISVs. They believe in providing maximum functionality with minimal disruption. NVIDIA will utilize the mechanisms described in question #2 to support all functionality, including deprecated features in OpenGL 3.0, for future OpenGL versions.
7) Will functionality marked as deprecated be slow on NVIDIA hardware?
No. NVIDIA understands the importance of deprecated features to many customers and will provide full performance, support, tuning, and fixes for all features on the deprecated list.
This Nvidia OpenGL 3.0 Beta Driver for Windows XP/Vista 64-bit provides a crucial stepping stone for developers transitioning to newer OpenGL standards, even though it is a beta release.
