From 60b08eb1fdf287d28ec66b9282513ab35a61aee0 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 31 Aug 2009 10:13:22 -0700 Subject: mesa: Make MultiDrawElements submit multiple primitives at once. Previously, MultiDrawElements just called DrawElements a bunch of times. By sending several primitives down the pipeline at once, we avoid a bunch of validation. On my GL demo, this improves fps by 2.5% (+/- .41%) and reduces CPU usage by 70.5% (+/- 2.9%) (n=3).
