As some of you guys have noticed, the Vulkan Backend inside the Dolphin Emulator has stopped working on our GPD XD+.

I've done some research and found that this is because the Dolphin creators have messed up with one of their recent refactoring attempts.

To get a properly working Dolphin build (with Vulkan support) out of their latest master-branch you will have to revert the following commits prior to building:

  • git revert a5534ec
  • git revert 21d81f9
  • git revert db67630
  • git revert 7f0111b
  • git revert f039149

For convenience's sake I've also attached an already fixed build of their latest version 9709.

For those that wonder (or simply want to stick with official Dolphin builds): The latest official version that works without these reverts is 9633.

Are you by any chance trying to install it on top of an existing Dolphin install? If so, you must first uninstall the old version to avoid a signature conflict. Keep in mind this is a patched version made by me... as such it is signed by my signature, which obviously is different to the one used by the original Dolphin developers. It's the only explanation I can come up with as to why you guys might have trouble installing it.

Wait a second. I think I know what you guys are talking about. Installing straight from Chrome can be a bit troublesome. Open the APK via the Documents application and install it from there.

is it faster than opengl? In PPSSPP vulkan is actually A LOT slower. You should also provide this fix for the Dolphin Team.

Sorry for the gravedig but how do you revert these values in order to continue using the latest dolphin builds? (I'd like to know so then when they release a new build I can continue to update the app while benefiting from the changes, rather than use an old outdated version.)

The current state of affairs is that the newest Dolphin builds have this issue fixed already. However, the OpenGL backend runs a LOT faster than Vulkan anyway. For a comparison: Vulkan on latest Dolphin gives me about 10FPS on Luigi's Mansion while OpenGL gives me 23-27FPS. Long story short: At this point you can just use the official daily Dolphin builds and they will work fine. Stick to the OpenGL backend though as it runs a lot faster with less glitches.

@Black-Seraph Could You please fix dolphin mmj APK? Or at least look into it if you can. The optimization for it goes far beyond the of dolphin and I can seem to get the performance taki udon gets regardless of all the changes and builds I download.
