Also consider this: ``` for (...) { glBegin(GL_LINES); glVertex3f(...); glVertex3f(...); glEnd(); } ``` We can't have correct `gl_VertexID` and `gl_PrimitiveID` even without display lists if we want drivers to process...

I think we can support `gl_VertexID` and `gl_PrimitiveID` with immediate mode `glBegin/End` if we disable draw merging when those variables are being used.

Can you try to switch const_uploader from DEFAULT to STREAM? If that's not enough, can you increase the size from 128 * 1024 to 1024 * 1024?
