I am working on a portable GUI toolkit for Linux and Windows and stuck on some performance problem. On several systems (as my netbook based on the infamous Intel GMA 3650) is very highly affected by the driver installed.
But what is the paradox, when the fallback VESA driver is installed, the performance of my code is much higher than with the dedicated proprietary driver.
I wonder what the state / performance of the open source ATI driver is now, when compared to the closed source driver for 'old' cards.
currently, I'm stuck with Ubuntu 8.10, as that's the last edition that comes with the 'old' ATI drivers, that support my ATI Mobility FireGL V5200 card. (which is 'old' according to ATI/AMD, even though it's a 3 year old top-of-the-line card).
Phoronix: Linux 3.12 Can Change AMD's Catalyst Performance
Due to a change found in the Linux 3.12 kernel, the AMD Radeon GPU performance is a lot faster with the open-source driver for certain configurations and the Nouveau driver performance is also faster depending upon the CPU and GPU.
tested with Ubuntu 10.04 (32bit) Using open source driver works out of box, it\'s good for Compiz, no tearing but 3D performance are low (games). Using ATI proprietary driver (Driver Hardware) 3D performance are very high and Compiz works, but is stron...
Phoronix: Radeon Gallium3D Performance Gets Close To Catalyst On Ubuntu 14.04
With the open-source graphics driver stack found in the forthcoming release of Ubuntu 14.04 LTS (Mesa 10.1 + Linux 3.13), the performance of the community-developed Radeon Gallium3D driver is now close to that of the official AMD Catalyst driver for recent generations of Radeon graphics cards.
I installed 13.10 On my pc and I have performance problems. After I type in my password I got an blackscreen for ~20sec. I tried to play Dota 2 to test the performance and it isn't playable. I use my system with 2 monitors and both work. I think there is a driver problem.
I see that my machine (Radeon HD 6290) has the option to choose either the X.Org X Server driver or the AMD proprietary driver:
I want to know which one is the recommended one in term of performance in general? Do one of them have an edge over the other? And apart from performance, is there any stability issue with them in general? How often are they updated?
Following performance benchmark results I published earlier this week comparing the open-source Radeon and AMD Catalyst driver performance under Ubuntu 12.10, Marek, the well-known independent open-source graphics driver developer, set out to explore some of the performance issues in the open-source driver.
