From 5628501e7b4289f5a04a2ca26d1ed4b3dec1a442 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 18 Dec 2012 16:05:24 -0800 Subject: [PATCH] i965: Start using HIZ for Z16 textures. I had left this out for a long time because it regressed some depthstencil-render-miplevels cases when it was enabled. Now that the bugs causing those are fixed, there's nothing stopping us. Improves glbenchmark 2.1 offscreen performance by 7.3% +/- 2.8% (n=10).
