I am currently using the xf86-video-ati.tcz driver. I would like to use the ATI propriety driver. I have ATI integrated graphics on board (Radeon HD R5E) with an AMD Embedded G-Series chipset. I am try to run a 3d application called openscene graph and need an fps boost. If any one has any other ideas please let me know.The application is constantly using 100% of the first core on my cpu and i would like to offload it onto my GPU.
It might be possible that you can use the new amdgpu or amdgpu-pro driver.
radeon (xf86-video-ati) is the open source driver for older AMD GPUs. amdgpu (xf86-video-amdgpu) is the new open source driver for new AMD GPUs.
The old proprietary fglrx driver is deprecated. It's successor is amdgpu-pro. amdgpu-pro is a proprietary extension to amdgpu.
However, without enabling it in the Kernel, amdgpu by default is supposed to be run only on AMD GCN (Graphics Core Next) 1.2 GPUs.
But: When enabling it in the Kernel, amdgpu can also be used on GCN 1.0 and GCN 1.1 GPUs. The Gentoo Wiki explains how to do this: https://wiki.gentoo.org/wiki/AMDGPU#Kernel
Now, the question is: Is the Radeon HD R5E that you mentioned a GCN 1.0/1.1/1.2 GPU? The Gentoo Wiki explains how to check this: https://wiki.gentoo.org/wiki/AMDGPU#Hardware_detection
Which chipset name do you get when looking it up using lspci?
