From c7c7b0088998a82a6f06f1a5d2546150ea6f4ffb Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Wed, 6 Dec 2017 17:49:20 +0100 Subject: [PATCH] radv: only re-mit the index type when it changes dota2 binds a ton of index buffers but the type is always 16-bit. Note that we have to invalidate the type when switching from indexed draws to normal draws.
