This article provides information regarding the Nvidia GeForce Ion Graphics Driver version 197.44, a WHQL-certified driver for Windows Vista and Windows 7. This driver release, alongside Linux driver version 195.36.07.04, brings full support for the OpenGL 4.0 and GLSL 4.00 standards, as well as OpenGL 3.3 and GLSL 3.30. This enhancement is crucial for users seeking to leverage the latest features and performance improvements offered by these graphics APIs in their applications and games.
OpenGL 4.0 and OpenGL 3.3: A Leap Forward in Graphics Capabilities
OpenGL (Open Graphics Library) is a cross-language, cross-platform API for rendering 2D and 3D vector graphics. It is a cornerstone of modern graphics applications, providing a standardized interface for software to communicate with the graphics processing unit (GPU). Each new version of OpenGL introduces new features, improved performance, and enhanced capabilities.
The Nvidia GeForce Ion Graphics Driver version 197.44 unlocks the potential of OpenGL 4.0 and 3.3 for compatible NVIDIA GPUs, allowing developers and users to take advantage of:
- Advanced Shading Languages: GLSL (OpenGL Shading Language) allows developers to write custom shaders that control how objects are rendered. Version 4.00 and 3.30 of GLSL offer increased flexibility and control over the rendering pipeline.
- Enhanced Texture Handling: New texture formats and functionalities allow for more realistic and detailed visuals.
- Improved Geometry Processing: Advancements in geometry processing enable the creation of more complex and detailed 3D models.
- General Performance Optimizations: Each new version of OpenGL typically includes optimizations that improve the overall performance of graphics applications.
Hardware Compatibility
Not all NVIDIA GPUs are capable of supporting OpenGL 4.0 or 3.3. The following outlines the hardware requirements for each version:
OpenGL 4.0 and GLSL 4.00 Support:
- Requires a Fermi-based GPU. This includes later generations of NVIDIA graphics cards.
OpenGL 3.3 and GLSL 3.30 Support:
- Desktop:
- Quadro FX 370, 570, 1700, 3700, 4600, 4700×2, 4800, 5600, 5800, Quadro VX200, Quadro CX
- GeForce 8000 series or higher; GeForce G100, GT120, 130, 220, GTS 150, GTS 250, GT310, 320, 330, 340, GeForce GTX 260 and higher, any ION based products.
- Notebook:
- Quadro FX 360M, 370M, 570M, 770M, 1600M, 1700M, 2700M, 2800M, 3600M, 3700M, 3800M
- GeForce 8000 series or higher
Users with older NVIDIA GPUs not listed above may not be able to fully utilize the features offered by OpenGL 4.0 and 3.3, even with the Nvidia GeForce Ion Graphics Driver installed.
OpenGL Extensions
The Nvidia GeForce Ion Graphics Driver 197.44 also introduces several OpenGL extensions, further expanding the capabilities of the API.
For OpenGL 2 Capable Hardware:
- ARB_texture_swizzle (also in core OpenGL 3.3)
- ARB_sampler_objects (also in core OpenGL 3.3)
- ARB_occlusion_query2 (also in core OpenGL 3.3)
- ARB_timer_query (also in core OpenGL 3.3)
- ARB_explicit_attrib_location (also in core OpenGL 3.3)
For OpenGL 4 Capable Hardware:
- ARB_texture_compression_bptc
- EXT_shader_image_load_store
- EXT_vertex_attrib_64bit
- NV_gpu_shader5
- NV_gpu_program5
- NV_tessellation_program5
- NV_vertex_attrib_integer_64bit
- NV_shader_buffer_store
These extensions provide developers with access to advanced features and functionalities that can be used to create more visually stunning and immersive experiences.
Using OpenGL 4.0 in Your Code
To utilize OpenGL 3.0 and later versions, including OpenGL 4.0, applications need to explicitly "opt-in." This is achieved through the CreateContextAttribsARB function (for WGL and GLX), which allows you to request a context that supports the desired OpenGL version.
For OpenGL 3.2 and later, including OpenGL 4.0, you must also specify the desired profile: either the "Core" or the "Compatibility" profile. The "Core" profile provides a cleaner, more modern API, while the "Compatibility" profile includes deprecated features for backwards compatibility.
NVIDIA recommends that developers create a "Compatibility" profile context to ensure full backwards compatibility with existing OpenGL code.
Deprecation and Compatibility
OpenGL has introduced a deprecation mechanism, marking features for removal in future versions. While deprecated features are still present in OpenGL 3.0, they were removed in OpenGL 3.1.
To address the need for both new functionality and backwards compatibility, the ARB_compatibility extension was created. This extension re-introduces all removed functionality back into core OpenGL 3.1. NVIDIA supports this extension across all its OpenGL 3 capable offerings, providing a fully backwards compatible OpenGL 3.1 implementation when the ARB_compatibility extension name is present in the OpenGL extension string.
Starting with OpenGL 3.2, two profiles were introduced: "Core" and "Compatibility." The "Core" profile builds on OpenGL 3.1 without ARB_compatibility and does not support deprecated features. The "Compatibility" profile builds on OpenGL 3.1 with ARB_compatibility and provides full support for all features, including deprecated ones. Both profiles are available in NVIDIA’s OpenGL 4.0 drivers.
Legacy Context Creation API
The "old" context creation API, WGL/GLXCreateContext, can still be used. However, for new code, NVIDIA strongly recommends using the CreateContextAttribsARB API. The "old" CreateContext API will create an OpenGL 4.0 "Compatibility" profile.
NVIDIA’s Commitment to OpenGL
NVIDIA is committed to providing maximum functionality and minimal disruption to developers. They fully support the ARB_compatibility extension and "Compatibility" profile, and ship OpenGL drivers without any functionality removed, including any functionality marked as deprecated.
NVIDIA has no plans to drop support for any version of OpenGL on existing or future hardware. Therefore, all currently shipping applications will continue to work on NVIDIA’s existing and future hardware.
