    Phoronix: Dota 2 Radeon OpenGL vs. Vulkan Performance With Mesa Git, Linux 4.9-rc1

    Now that the RADV Radeon Vulkan driver has landed in Mesa Git and Linux 4.9-rc1 is out, I figured it was time for some fresh benchmarks of the Radeon Vulkan driver against the RadeonSI Gallium3D OpenGL driver. Here is the first of that new data.

    Vulkan: Is somebody able to successfully run Dota 2 on R9 290/390 or on some other GCN1.1 GPU? The machine becomes unresponsive right after the title screen appears.

      That's very close to 60 fps... disable vsync not working?

        Probably weird 2560x1600 resolution, not sure why Michael decide to pick up that now when screen is 4K... also RX 480 with GL seems a bit faster on 4K here

          On my 290 (Linux 4.7.7, amdgpu, using mesa-git repo for Arch) first time I had "Failed to initialize Vulkan. Please make sure your driver and GPU support Vulkan." Fixed by removing vulkan-intel package.

          Second time it locked up straight after the menu but mouse pointer still moved (couldn't restart X or change TTY in that case). With Linux 4.8.1 I could get into a game but lots of rendering glitches (mostly on the ground) and the whole system froze after 5 minutes, leaving a hard reset as only option.

          Incidentally, I get a lot of system freezes with the 4.8 kernel just while doing nothing more intensive than using Firefox. 4.7 is fine.

            The same on GCN 1.0, verde.

                Probably works the best on author card... goal of stability and scalability down from the Temash up to the Fiji will be ignorant and long

                  Are you just compiling your own amdgpu enabled 290 kernel or are you getting it from somewhere? I'd love to try some of these amdgpu features on my 290 but would rather not leave my PC on all night compiling the kernel for it.
