AMD Catalyst For Linux On The "Blacklist Of Junk"
Phoronix: AMD Catalyst For Linux On The "Blacklist Of Junk"
While the Catalyst Linux graphics driver was overhauled five years ago, not everyone is satisfied with the closed-source AMD Radeon Linux graphics driver. Here's some interesting comments by a prominent Linux developer and his less than stellar Catalyst experience...
Considering that KWin sucks with fglrx I can probably guess who this is...
And if you think it's Martin (KWin), your guess is wrong.

You will get so many bug report from their users, that it's just a good idea to stop bothering and blacklist their driver. Driver are maybe going better for games, but compositor is another story. If you want something stable and fast, you will be better with your own software scenegraph backend.
And I know exactly who did send this mail. He will surely release some Window/Composite Manager by the end of the year and people have been speaking about this for sometimes now :-)
Soo... let me get this straight: 2 f*king years ago, some unnamed developer said fglrx was bad. And now, Michael posts an "article" claiming the driver is on a "blacklist of junk".
Very solid piece of journalism Michael, well done...
The open source radeon and nouveau gallium drivers, as well as the open source Intel drivers should also qualify for this blacklist. The Intel drivers for Linux has worse OpenGL support than the Windows driver, especially GLSL. But it handles old style OpenGL fine and reasonable stability. Fglrx has very good features on paper, but generally fail to deliver. Fglrx has general GLSL and OpenCL stability issues, and has a semi-featured configuration utility. Its like a product which is almost ready for shipping, with a lot of potential but missing the final touch to make it a finished product. Compared to Intel (Linux), Fglrx has more support and does GLSL better, but the end user experience would depend on usage. But for modern OpenGL, Fglrx is still way better than Intel (Linux). The Radeon and Nouveau gallium drivers has still way worse OpenGL support than Fglrx, and has a very variable stability from release to release.
This is just a suggestion, but it would be great if your reviews in the future could include more information regarding the frame rate and potential stuttering. Average frame rates is not everything, especially now as both Nvidia and AMD are adding boost which "only" improves the maximum frame rates which raises the average frame rate. And regarding stuttering, even the good Nvidia drivers does from time to time have a release with some X Server bugs which makes games lag, especially during a lot of IO events (e.g. mouse movement). An average frame measurement would not be able to detect these kinds of problems.
fglrx is much better now except with fedora which is full crap anyway.
No.. it might have improved on newer cards but it still is quite terrible on my radeon 4200 with the latest version that will run. Works fine for 2d but texturing is wonky in wine... Mesa works fine however and even allows greater dx versions to be used than fglrx.
just dont say such stupid stuff. you absolutate speed and feature set, thats retarded. there is more than this 2 categories out there.

They are more way more stable than the closed ones and they are free, and they are fast enough for 3d desktop. So for all people who not want to play under linux because there are anyway no high grafics opensource games, and even this source-engin2 games are that crappy 10 year old grafics quality that it will even run with the intel-igps...
so yes for commercial game developers you can maybe if you make really high quality (graphics wise) games blacklist this drivers, but for the 99% of the other people you cant.
