3D News, GL, DirectX "Open-source support has appeared by default in X.Org 7.1 for R300 generation GPUs. While ATI does not officially support these R300 open-source drivers, this alternative have been gaining momentum with users largely due to the lack of GLX_EXT_texture_from_pixmap support in fglrx. This extension is needed for the AIGLX desktop eye-candy. These drivers do lack TV-out support and many other features found within ATI's fglrx drivers, but how does its performance compare?"

"One of the other benefits from these drivers come in the form of supporting AIGLX with the GLX_EXT_texture_from_pixmap extension (not to mention the psychological benefits of being able to get by without using binary-only drivers)."

I could care less if I'm using open source drivers or not. What I want in drivers (of any kind) is performance and reliability. When there are differences in performance of 44fps to 131fps it's no contest.

No, this guy is probably not on crack.

It is arrogant and ignorant to believe your own preferences are the only reasonable ones.


I also work on a PC with an ati r300 card in it. The proprietary driver sucks. I can't change the modeline with xvidtune, and the default one makes my monitor do a high frequency noise. GLX_EXT_texture_from_pixmap is missing, as the author pointed out. Suspend to disk doesn't work right.

It seems it is a big mess and the *only* thing working better would be OpenGL accelerated games. Even benchmarking the XRender speed revealed there was no big difference (in 2D accel. performance, that is). As I don't want to play games, but instead to get work done, you're right, there is no contest, as the proprietary driver just sucks and is kind of unusable for me.

As a consumer savvy enough to understand the issues, it pays to balance the factors against each other. Open drivers give you certain assurances and conveniences. Performance is also a factor... *if* you play games or do other things that require 3D. Otherwise, the performace differences count for zip. Reliability is quite significant.

Your mileage may vary.

I'm quite happy with the open drivers on my notebook with an ATI Express 200M. The performace in glxgears is about half what the fglrx drivers can do, but I don't care. It's less hassle not having to muck with the proprietary drivers.

I do use the proprietary NVidia drivers on my desktop machine.

I'd say more, but I think I'll go back to trying to find a way out of my current level in 'Rune'. ;-)

Well, the problem is that the benchmark regarded the only closed source drivers advantage: 3D performance. Search for fglrx drivers on Google, or on the most important linux forums or mailing lists, you'll get an infinite list of complains. If my memory does not fail me in the last years the closed source drivers released by ATI broke (or are still breaking) a number of things, including switching to a console from X and switching back. To not mention that ATI notoriously release the drivers seldom and untimely. This was not a problem some years ago, but now the X.org development has a different pace, and ATI users are forced to lag back for months with outdated software.

There's also no contest when your ATI hardware is part of a PPC-based iBook and you want to run some version of Linux. In that case, performance for the binary drivers is a whopping 0 fps for everything.

I for one am very glad there are open source ATI drivers, and I hope development on them continues. Improvements in their performance is just gravy.
