Phoronix: Mesa 21.3 Enables NGG Culling By Default For RDNA2 GPUs

The Radeon Vulkan driver "RADV" within Mesa 21.3 is enabling NGG culling by default for Radeon RX 6000 series (RDNA2) GPUs and newer as another performance win...

Is this already done for OpenGL or not?

To my knowledge no, however, this (skip to implementation details if it doesn't automatically) suggests it was actually ported over from the RadeonSI (?). If RADV's NGGC isn't the same thing whatever RadeonSI has already supposedly implemented then no, it probably won't be added for quite some time as it was just declared stable for Navi20. After all, ACO is still yet to be ported to RadeonSI.

EDIT: Read the post below mine. Somehow I managed to miss the fact that this article was about RadeonSI not RADV.

There is working NGG code in radeonsi OpenGL today, although I'm not sure if it is enabled by default yet. It was disabled for RDNA1 recently, but I *think* it is enabled by default for RDNA2.

Yes, as far as I know it's enabled by default in RadeonSI on GFX10.3
