From 18bdf73556440ca2eaac2d22e1e3ebe1be7b6c1d Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Wed, 4 Oct 2017 01:08:37 -0700 Subject: [PATCH] mesa: Use a 565 format for GL_RGB and GL_UNSIGNED_SHORT_5_6_5 textures. Found while trying to optimize an application. Not observed to help performance on i965, but should at least reduce the memory usage of such textures a bit.
