View Full Version : occlusion queries + instancing?

03-20-2009, 12:45 AM
Hello, does anyone know of a way to use geometry instancing with a seperate occlusion query per instance?

I've noticed that using pseudo instancing + occlusion query per instance effectively disables pseudo instancing(large drop in performance vs not issuing the occlusion queries).

GL_EXT_draw_instanced appears to just use a single draw call so I unless there is a new occlusion query api I missed, only one OC could be issued...
