Nvidia OpenGL 3.0 Beta Driver for Windows XP

This article provides information regarding the Nvidia OpenGL 3.0 Beta Driver for Windows XP. This driver was specifically designed for developers looking to explore and implement the new features introduced in OpenGL 3.0 and GLSL 1.30. It’s important to understand that these features are not enabled by default and require a specific process to activate.

Target Audience and Purpose

The primary audience for this driver is developers. Its purpose is to provide a platform for experimentation and development with the OpenGL 3.0 and GLSL 1.30 specifications. By offering this beta driver, Nvidia aimed to allow developers to start adapting their codebases and take advantage of the new capabilities offered by these updated standards.

Enabling OpenGL 3.0 Features

Unlike Linux drivers, where OpenGL 3.0 functionality is inherently enabled, the Windows XP driver requires an extra step. To enable the new features, developers need to utilize the nvemulate utility. Detailed instructions on how to use this utility can be found on the Nvidia developer website: https://developer.nvidia.com/object/nvemulate.html. This utility essentially emulates the OpenGL 3.0 environment, allowing developers to test and debug their code.

Supported Hardware

Not all Nvidia graphics cards are compatible with this driver and the OpenGL 3.0 features. The following lists the supported desktop and notebook GPUs:

Desktop:

Quadro FX 370, 570, 1700, 3700, 4600, 4700×2, 5600
GeForce 8000 series or higher; GeForce GTX 260, 280

Notebook:

Quadro FX 360M, 370M, 570M, 770M, 1600M, 1700M, 2700M, 3600M, 3700M
GeForce 8000 series or higher

It’s crucial to ensure your graphics card is on this list before attempting to install and use the driver, as it will not function correctly on older hardware. The new features in OpenGL 3.0 require G80, or newer hardware. Thus OpenGL 3.0 is not supported on NV3x, NV4x nor G7x hardware.

Implemented Functionality and Limitations

This beta driver implements the majority of GLSL 1.30 and OpenGL 3.0 specifications. However, some features were not included in this initial release:

One-channel (RED) and two-channel (RG) textures
The Clearbuffer API
Windowless rendering support (Nvidia suggests using GPU affinity instead)
Forward-compatible context
Debug Context

Developers should be aware of these limitations when planning their development and testing strategies.

New Extensions

The driver introduces several new extensions, expanding the functionality available to developers. These extensions include:

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

These extensions provide access to advanced rendering techniques and capabilities within the OpenGL framework.

Improvements Over Previous Beta (177.89)

This beta driver includes several improvements and bug fixes compared to the previous Windows beta driver release (177.89):

Linux Support: OpenGL 3.0 and GLSL 1.30 functionality support is now identical between the Linux and Windows releases.
FBO Rendering: Rendering to a Framebuffer Object (FBO) with mixed-size attachments is now supported.
VAO Enhancements: Bug fixes and performance improvements have been implemented for Vertex Array Objects (VAOs).
EXT_texture_swizzle Support: Support for the EXT_texture_swizzle extension has been added.
Transform Feedback: Missing functionality related to transform feedback has been implemented.
Bug Fixes: Various other bug fixes have been incorporated to improve stability and performance.

These enhancements make the driver more robust and feature-rich for developers working with OpenGL 3.0.

Accessing Specifications and Reporting Issues

The official OpenGL 3.0 and GLSL 1.30 specifications can be downloaded from the OpenGL registry: https://www.opengl.org/registry/.

For any bugs or issues encountered while using the driver, Nvidia encourages developers to report them through the developer website: https://nvdeveloper.nvidia.com/. This feedback is crucial for improving the driver and ensuring a stable and reliable development environment.

OpenGL 3.0 on NVIDIA Hardware: Frequently Asked Questions

The original release included a FAQ section to address common concerns and questions regarding OpenGL 3.0 on Nvidia hardware. Here’s a summary of the key points:

How to Start Using OpenGL 3.0: Applications must explicitly "opt-in" to use OpenGL 3.0 by using the CreateContextAttribsARB function (defined in the WGL/GLX_ARB_create_context extensions). If you use existing context creation calls, you will get OpenGL 2.1.
Deprecation and Functionality Removal: OpenGL 3.0 introduced a deprecation mechanism, marking features for removal in future versions. While not removed in OpenGL 3.0, these features may be removed later. Nvidia plans to provide mechanisms (profiles or extensions) to support these features even if they are officially deprecated.
Existing Application Compatibility: Nvidia has no plans to drop support for OpenGL 2.1 and earlier versions. Existing applications will continue to work on current and future Nvidia hardware.
Hardware Support: OpenGL 3.0 requires G80 or newer hardware. It is not supported on NV3x, NV4x, or G7x hardware.
Future Functionality Removal: Nvidia has no interest in removing features relied upon by ISVs. They will leverage the deprecation mechanism to continue supporting all functionality.
Performance of Deprecated Features: Functionality marked as deprecated will not be slow on Nvidia hardware. Nvidia will provide full performance and support for these features.
