Originally posted by Ancurio View PostI have used legacy for about a year, a couple weeks ago I was finally forced to switch back to open source when upgrading Fedora 17 -> 19. As many people will say, 2D desktop performance is great (scrolling much smoother). However, my 2D engine only runs at about 70% of the catalyst speed (unless I use "high" profile). Also, timer queries perform really weird on the FOSS driver because even after a full frame cycle after having ended the query, the results will still not be available for quite some time (this never happened on legacy). Other than that the FOSS driver is pretty cool, and finally being relieved from the fear of Xorg/Kernel updates was definitely worth it.
2) File bug. Get to IRC. Maybe You will even get fix in 3h time

Meanwhile, my HD 4870 machine runs pretty awesomely with open source drivers; certainly better than Catalyst does on that card. Only thing is, to get the most out of open source drivers you do need to create an Xorg.conf, and it is a good idea to have the latest kernel.
My Radeon HD 7950 runs fairly well on open source now, but it's still much better to use Catalyst. This new Catalyst driver fixed a lot of bugs I had with the last beta.

With recent AMD moves to open up hw specs and adding devs to the open source driver effort I think that AMD long term goal for the drivers is obvious.
However the transitory period is very painful. Each driver has its strength and weaknesses.
Want good opengl perf and good opencl 1.2: Catalyst
Want HW video decoding: open source
I just found out that xvba not only do not support MPEG4, it just doesn't work at all for some time:
I have a dream. Next week AMD will announce that it fully release the source code of catalyst. It that was to happen in less than a week, AMD would rule Linux graphics world with all the volunteers around the world fixing bugs and improving perfs. (It took less than 3 days after AMD release HDA controller for HDMI sound to have a working 7.1 HDMI sound driver!) Just dreaming....but would the best thing to happen for AMD product Linux owner...
