From 22b417b75ce0e6658a5d1e0e80cb6c3fdf631774 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Fri, 1 May 2009 18:20:42 +0100 Subject: [PATCH] mesa/main: set PREFER_DP4 to match position_invarient code This is a quick fix for z fighting in quake4 caused by the mismatch between vertex transformation here and in the position_invarient code. Full fix would be to make this driver-tunable and adjust both position_invarient and ffvertex_prog.c code to respect driver preferences. --- src/mesa/main/ffvertex_prog.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/mesa/main/ffvertex_prog.c b/src/mesa/main/ffvertex_prog.c index 1ce5685af45..82e1c4af665 100644 --- a/src/mesa/main/ffvertex_prog.c +++ b/src/mesa/main/ffvertex_prog.c @@ -319,7 +319,7 @@ static void make_state_key( GLcontext *ctx, struct state_key *key ) * multiplications with DP4's or with MUL/MAD's?
