    Dolphin Emulator Vulkan Crash

    xperia64

      Hello,

      I recently bought a device with an Intel Core m3-7y30 with Intel 615 graphics, and it would seem that the iGPU is incompatible with the Dolphin emulator when using Vulkan as the renderer under Windows.

      The memory leak issue described in this thread doesn't seem to happen any more: Huge Memory Leak + System Lockup with Vulkan on Dolphin Emulator but the program outright crashes when loading any game or homebrew.

      I figured this may be worth trying to bring up again, as recently Dolphin started working with Vulkan on mobile Adreno graphics, which in the past have been more problematic than Intel graphics.

       

      In terms of getting a sample program to load in Dolphin, I have found that this freely available, legal, GPL-licensed Starfield homebrew demonstrates the issue: Starfield - WiiBrew

      Under OpenGL and Direct3D 11, the Starfield demo seems to render correctly. Under Vulkan, Dolphin appears to completely crash. Developers of Dolphin seem to have indicated this is likely a driver problem.

       

      I am on Windows 10 1803 64-bit with graphics driver version 24.20.100.6194.

      I have confirmed that the Vulkan runtime is installed and functional on my system as other Vulkan programs run as intended.

      In addition, when I booted Ubuntu 18.04 on this same device, Dolphin was able to run correctly using Vulkan as the renderer, indicating that hardware is compatible.

       

      When Dolphin supported Direct3D 12, it ran much faster than under OpenGL or Direct3D 11 as expected, but since that is no longer an option in current builds, we need Vulkan to work to provide the same performance.

       

      I can provide more logs and system information if required. I can also test drivers and configuration settings on an Intel Core i5-7200U w/620 graphics and an Intel Core i7-7700k w/630 graphics if that would help as well.

          Sorry, didn't see the recommended device info table when I first posted this.

          1. Download and run Dolphin Emulator
          2. Download Starfield Demo
          3. Select Graphics Options
          4. Change Backend to Vulkan
          5. Select Open and select the "starfield/boot.dol" file
          6. Dolphin crashes

              Hi, the timing seems to be a coincidence, but I posted the requested information right before your post yesterday. I just want to be sure it gets noticed.
