Hello,

I update my project from UE4.26 to UE5.2, then I find the 8K video only get less than 10fps in both pico and quest. When In UE4.26, the 8K video could play with 72fps+.

One possible reason is the change from opengl to vulkan. I don’t know how to solve this problem.

Thanks.

Hi Andy,

I’ve moved this post from the C++ section to the XR Section.

Hi, yes that issue is due to Vulkan. We haven’t upgraded our engine because of that.
This issue is around since at least 2 years now.

Unfortunately Open GL is not supported much longer so you won’t be able to switch it.
