Hi there, I am creating an app that will display 3D content and 360 video content for a business client.
If I package the app with ES3.1 everything runs smoothly up to 8k material at 90fps and looks great… but if I package the app with Vulkan I don’t even get 36fps and the GPU starts glitching, that’s the case even with fullHD material, i also encountered this Problem with ue4 4.26 
Does somebody know where the problem lies and how to fix it?
Hi, this is still an issue.
On 4.27 and 5.0 using Vulkan 8k Videos are just lagging under 20fps.
On 4.26 I was able to use OpenGL 3.1 and it worked without lag once switching to Vulkan the frames drop under 20fps.
This is a serious issue and needs fixing and a solution asap.
Can confirm, think Vulkan needs work but right now openGL doesn’t work on 5 and 5.1
What is the video content format? MP4, DASH or HLS? Maybe HISPlayer can help you? We support seamless Vulkan 8K video streaming on Oculus/ Meta Quest devices.
