From: Marek Olšák <marek.ol...@amd.com>
This bypasses _mesa_update_state_locked.
Before:
DrawElements ( 1 VBOs, 4 UBOs, 8 Tex) w/ stencil enable change: 3.99
million
DrawArrays ( 1 VBOs, 4 UBOs, 8 Tex) w/ stencil enable change: 4.56
million
After:
DrawElements ( 1 VBOs, 4 UBOs, 8 Tex) w/ stencil enable change: 4.93
million
DrawArrays ( 1 VBOs, 4 UBOs, 8 Tex) w/ stencil enable change: 5.84
million
It's quite a difference in the draw call rate when ctx->NewState stays
equal to 0 the whole time.
