From eb4dc547885994cc7961f7996c33ff484f664964 Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Fri, 23 Apr 2010 11:56:06 +0200 Subject: [PATCH] r600: don't enable depth test if there is no depth buffer If there is no depth buffer bound to current context don't enable depth test. GL states that if depth test is enabled without depth buffer it's as if depth buffer always pass.
