    Default AMD Radeon R9 290 On Ubuntu 14.04 With Catalyst Can Beat Windows 8.1

    Phoronix: AMD Radeon R9 290 On Ubuntu 14.04 With Catalyst Can Beat Windows 8.1

    The latest Linux graphics testing under the microscope at Phoronix is comparing the Ubuntu 14.04 LTS vs. Windows 8.1 performance with all available updates. Results from Intel, NVIDIA, and AMD hardware is coming up next week while today is a bit of a preview of the AMD numbers when using a Radeon R9 290 "Hawaii" graphics card. While the open-source AMD Hawaii support remains broken, with the Catalyst 14.4 driver on each operating system, the Linux Catalyst driver with the R9 290 graphics card can outperform Windows 8.1 Pro with some OpenGL games and benchmarks.

    Hmm this is very interesting. I think this is the first time the linux catalyst drivers were doing better in every single test (though, there weren't that many tests). I might switch back to catalyst if AMD will look into wayland support.

    Probably they're shifting focus on OpenGL to Linux instead of focusing Direct3D and OpenGL on Windows and let OpenGL Linux starve. I think it should be the same as the codebase is supposedly shared.

    I would like to see a test of some source games to compare as well.

    Bridgeman stated something else, you are probably mistaken nvidia's share code over both platforms, amd's is not largely shared.

    Probably "less shared" is more correct than "largely not shared". Most of the OpenGL and OpenCL code is shared, however the parts which talk to the kernel driver (think libdrm/winsys in the open stack) are different.

    Won't Linux beat Windows every time (if all things were equal) because of WDDM?(since Vista) Shifting most of the kernel space drivers in to the user space to keep the video card from crashing the system

    One site says that Gallium3d+PTE+3.15+hyperz is kicking Catalysts anus in Steam games. My experience with Catalyst 14.4 has been slower then open source, in both Portal 2 and Wine. Catalyst for me has been stutter in fps and lower fps overall. This is on my Radeon HD 6370M. Though Catalyst for me does a better job at keeping my laptop cool.

    If we tend to believe one Gentoo user, we are all badly wrong . That is severely young all git code, i expect "unexpected" there bugs too . But also keep in mind that is on Gentoo, so those parts of the graphics stack is heavely optimized for that one machine and that also can break somewhere . That is like overcloking, i can overclock my APU and beat Catalyst, and he can build his kernel with some patches which might also break Catalyst performance but improve radeon, so we can't really know that from one Gentoo user experiance .

    And that needs to be tested and approved by other people, so there is no reason for everage Joe to be so happy right now .

    I said "not largely shared", "Largely not shared" feels like an completly different statement. The first could mean 65% is shared while the second probably means 35% is shared.

    But I stand corrected, makes me look different at opengl test results and changes.
