UE4 / Quest / Vulkan - Proper Render/Project Settings?
Tried creating a simple test project with both the Oculus UE4 branch and Epic's latest 4.22 branch and if I enable Vulkan (ES2 and ES3.1 work fine ) I always get a crash on application launch. Tried all the settings I could find across the various Oculus and Epic documentation. Does anyone have this working currently that could share their basic project settings? Is it just broke in 4.22?
Thanks
Thanks

- I too had to disable Vulkan to get my project to NOT crash, I feel your pain, I want that Vulkan performance boost.
- Same question here:On https://developer.oculus.com/blog/down-the-rabbit-hole-w-oculus-quest-the-hardware-software/ it states the Quest supports Vulkan. UE 4.22 also supports Vulkan. So why does even the most simple app deployed on the Quest that uses Vulkan crash at launch?Edit: according to this post, you need to disable multi-view and FFR for Vulkan to work. Will test asap but wouldn't fps drop a lot by doing so?Edit2: No luck. at least I see my splash screen at loading. Immediate crash afterwards.Edit3: apparently it still needs a future Oculus Quest runtime update for Vulkan to work.
- Same issue here: Blank project app crashes on launch when Vulkan is enabled.
But it runs after disabling MultiView (FFR was already off). Also switched on arm64. - Did you guys ever figure this out?
No and there has been no OS updates to support FFR/multi-view with Vulkan on Go/Quest, yet.
Now there is Vulkan support (even on Go, although partial)- Has anyone tried this with the Oculus version of Unreal?
- Working now, however you still cannot use chromatic aberration correction as it results in a crash.
- Just tried it out on 4.22.3, definitely seeing a performance increase on my Quest project.

Do you mind running a test case for GPU particle on your Quest? https://developer.oculus.com/bugs/bug/352218849045408/
I don't have Quest, but it crashes on my Go.
