It has been very hard to saturate CPU. spawning more threads does not up CPU usage. The limit is uploading meshes to the GPU. the vulkan driver can't keep up I think.

#

I have a pretty big CPU

#

so that helps

Yeah I have observed the same bottle neck. The meshing is super fast but it takes time to stream to GPU

best I've done is like 50% CPU util

Currently playing with idea of using compute shaders to inflate compressed chunks

#

the frame rate dies cause the main thread is busy uploading meshes

Like geometry shader

Crazy when compared to Java shitshow Minecraft lol

I'm happy with the performance. I'm aware leveraging the GPU could help but I want to keep the GPU for graphics processing and not bog it down either.

#

yeah... Bedrock is pretty fast tho.

#

I played the first Bedrock release back before it was a cloud of microtransactions and I was impressed at chunk gen.

I mean geometry shaders were kinda invented for this task

#

But yeah, i need to go to sleep now
