What 3Dfx MVP AGP Professional driver development consists of? Are you given a certain task of, let's say, creating a module for the OpenGL drivers, or patching a certain bug in the last release, or? I can only speak from the 3dfx Tools side of things.
The whole tools project was initiated by the Belfast office 3Dfx MVP AGP Professional number of years ago, when we were still STB. It's goal was to provide a simple interface to all driver tweaks across a wide range of graphics cards.
3Dfx MVP AGP Professional As the tools is a long term project, it is a tight team that has been working together for several years. Initially the project was specced, with everyone having a share in authoring the documents.
The whole project was split into modules that were divided into the following areas: I worked on the full range, but I 3Dfx MVP AGP Professional to specialise in the driver controls and driver interfaces. Sustaining Engineering involves fixing bugs and adding new features to legacy products Voodoo2-Voodoo5.
All bugs are entered in a bug database with a full description of how to recreate the bug and how severe the bug is. Each entry in the database is then assigned to a particular engineer. All major bugs have to be fixed before each new driver release.

The driver development work is not as modular as the 3dfx Tools work. In the Belfast office people 3Dfx MVP AGP Professional to specialize in certain areas. I mainly work in Direct3D. How was the software development for 3dfx split up between you the Irish and the American team, and between the 35 people 35, right? There were 3Dfx MVP AGP Professional developers and 6 Quality Assurance staff in the Belfast office. Of these developers, 1 was multimedia - developing drivers for the Voodoo TV, 6 were the entire tools team, and the rest were the Sustaining Engineering department.

There are more engineers in the building that originally worked for STB, but they were spun off to form Enseo, for high end multimedia and video products. All the Tools work was done in this office. For the drivers, the main core was developed by the engineers in San Jose and Dallas, with the Sustaining Engineers taking care of legacy products. By legacy I 3Dfx MVP AGP Professional the Voodoo5!
The core work and driver set was developed in the states and generally a while before release Belfast took control, fixing any bugs that were left. What does driver optimization mean?
How do you "tweak" drivers for maximum performance? You change certain core routines to assembly language, or change something algorithmically, or? How can someone do a tweak in the driver that 3Dfx MVP AGP Professional this much performance, but was not possible to implement in the first release? Or is this due to the timeframe, that companies have to keep with product releases, in other words, is there no time to fully get to know the hardware before writing drivers?
Most of the core 3dfx routines are written in assembly, to get the maximum performance possible, but the rest of the driver was written in C. As far as I know, only the most commonly called code segments were in assembly, as it would take 3Dfx MVP AGP Professional long to write the entire driver like this. You are correct, a lot of it has to do with time. Coding large optimised routines in assembly take a lot time to write comparing to writing it in C.
Some of the large performance gains have been a result of examining the code generated by the C compilers and spotting segments that could have been done better. There are also tools that were used 3Dfx MVP AGP Professional the performance team to help them in 3Dfx MVP AGP Professional analysis VTune I think was one of them. In addition to what Paul has stated it is a fact that the more you work with a particular piece of hardware, the more familiar you become with it.
A better knowledge of the hardware allows software developers to write better code for it, often with tricks and workarounds that improve performance.

For example look at the first Playstation games that came out and compare them to the latest Playstation games. The game developers are using the same hardware but they are more familiar with it. I know that a few clever software tricks that significantly improved performance in later drivers.
