GPU Residence Drawer in Unity ECS

[pseudo panther]

I haven't really found anything on this online, so, can the GPU Residence Drawer be used inside of Unity ECS, using Entities Graphics, and if not, are there any plans for allowing that?

Well Entities Graphics have their own solution for Instansing

If you using DOTS just use Entities Graphics

I think the resident drawer just uses the BatchRendererGroup api, which entities graphics has always used. So they're basically doing the same thing.

Btw for Residence Drawer shader should support Entities Graphics (DOTS Instansing)

[frail grotto]

Actually, yes, absolutely the same thing
Entities Graphics also require Forward+

I haven't found any hints of a difference in how they work

But of course Entities Graphics will be faster since it works with Entities, not GameObjects

The only difference is that Enitities Graphics has been around for a long time, but I've never heard of GPU Resident Drawer before

Although they came out almost at the same time

I would say that GPU Resident Drawer is Enitities Graphics for GameObjects

Thanks a lot! I will take a closer look into Entities Graphics optimizations then. Still, there are features, like GPU occlusion culling that are based on the GPU Residence Drawer, so I suppose these do not yet exist in Unity ECS?

Yes
