First I want to say thank you to the author for his great work and effort.
I am using Vulkan.
I am using a Lenovo A3 and my brother is using a quest 3 and we have the same problem.
I can see the splats on device.
However the splats seem to quickly go from unsorted but visible to a very sparse set of shimmering splats.
When I set the number of frames between sort to a high number it takes longer for the splats to fade away.
If I don't sort at all, All splats are there but out of order and don't change.
So the sort is the problem.
Using Vulkan it does not complain about the wave intrinsics.
So as far as I can tell the sort is trashing my splats. I know there's an older version of the sort in the 0.7 version of the project but I haven't been able to fix using that. Anybody have a fix to the sort algorithm or different GPU sort or any other ideas on how to fix this?
