Reading Time: 3 minutes

The OpenGL Driver is software that enables your graphics card to communicate with the application that uses it. This is important if you want to play your favorite games on your PC.

Several different companies develop drivers for the OpenGL API. It is also important to update your drivers regularly in order to keep your system running properly.

Vendor A OpenGL Driver:

There are three vendors that provide OpenGL Drivers in Linux: NVIDIA, AMD, and Intel. In addition, there is a software implementation of the OpenGL API done by Mesa.

GL is a user-friendly, extensible, and easy-to-use graphics standard. The library is open source, and developers can find documentation, books, and tutorials to learn about it.

However, it is not a fully functional interface, and its implementation can be a stumbling block for some developers. Some features are not supported, and some hardware vendors do not provide drivers for certain types of GPUs.

The OpenGL Driver family is made up of vendors that support the GL standard and provide a user-friendly API. Some of these drivers are closed-source, but others are written by developers on their own.

Vendor A supports a lot of extensions (some of them quite a state of the art) that more or less work. They can’t get key stuff like queries or syncs to work reliably, so any extension that relies on this kind of synchronization is a disaster.

Vendor B OpenGL Driver:

The OpenGL Driver provides an interface for computer software to use the OpenGL graphics API on a specific graphics card.

Almost all PC games and applications (including games in the Windows Store) use the OpenGL API to render graphics on the computer’s display.

Vendor B of the OpenGL Driver family has a history of doing things like internally replacing entire shaders for key titles to make them perform better (sometimes much better). Most drivers probably do stuff like this occasionally, but this vendor will stop at nothing for performance.

This means you, as a “Joe Graphics Developer”, have little chance of achieving the same technical feats in your title (even if you use the exact same algorithms!).

Because you don’t have an embedded vendor driver engineer working specifically on your title making sure the driver does exactly the right thing (using low-level optimized shaders) when your specific game or engine is running.

Another key feature of this driver is that it has layers upon layers of cruft tacked on over. The years by devs who left and didn’t understand these barnacle-like software layers enough to safely change them.

The driver remains a tangled mess of code that can’t be updated without breaking something, and nobody remaining in the organization knows these software layers or how to fix them.

Vendor C:

OpenGL is an open-source graphics library that supports 2D and 3D vector graphics. The API is now being phased out in favor of Vulkan.

Vendor C of the OpenGL Driver family is a good solid driver, with excellent performance on most hardware. However, it has some historical faults and tends to stall when things go wrong.

In particular, it will never update a buffer the D3D9/11-style way without constantly stalling the pipeline (unless it is specifically a BufferSubData or Map). This has always been problematic for Valve devs who have 100% held this driver’s hands.

On the other hand. This vendor is incredibly savvy and strategic about embedding its driver engineers directly into key game teams to make sure everything works.

This can be a double-edged sword as it means you. As a “Joe Graphics Developer”, have little chance of achieving the same technical feats in your title (even if you use the exact same algorithms!).

Because you don’t have an embedded vendor driver engineer working specifically on your title making sure the driver does exactly the right thing (using low-level optimized shaders) when your specific game or engine is running.

Vendor D:

OpenGL is a graphics API that allows computers to communicate with graphics hardware. It is supported in all three major desktop platforms (Linux, Windows, and macOS).

Some graphics hardware supports basic hardware accelerated OpenGL implementation. These are called “core profile” drivers and provide some performance benefits over the software OpenGL.

For the best performance, use a driver that supports a 3-D Device Driver Interface (DDI). The DDI enables many OpenGL functions to be executed directly in hardware by the video card instead of being run in software on the computer.

This is the highest level of OpenGL support and requires the most effort to develop. The DDI driver also provides an additional layer of protection from malicious code running. The software rendering mode may cause problems with the hardware.

In general, vendor D tends to have a much higher quality driver than Vendor #1. But, it is far behind on the latest GL standard and will often refuse. So to work with modern extensions (e.g. glTexStorage) when running shipping titles that require them.
