R200 requires this since DP4 is used in hw tnl mode. R300 prefers it (should be faster due to no instruction dependencies), but both methods should be correct (when sw tcl is used though, MUL/MAD might be faster). Probably doesn't make much difference for R100 since vertex progs are executed in software anyway, but let's just keep it the same there too. --- diff --git a/src/mesa/drivers/dri/r200/r200_context.c b/src/mesa/drivers/dri/r200/r200_context.c index c06751516eb..058296eab23 100644 --- a/src/mesa/drivers/dri/r200/r200_context.c +++ b/src/mesa/drivers/dri/r200/r200_context.c @@ -405,6 +405,8 @@ GLboolean r200CreateContext( const __GLcontextModes *glVisual, ctx->Const.MaxDrawBuffers = 1; + _mesa_set_mvp_with_dp4( ctx, GL_TRUE ); + /* Initialize the software rasterizer and helper modules. */ _swrast_CreateContext( ctx ); diff --git a/src/mesa/drivers/dri/r300/r300_context.c b/src/mesa/drivers/dri/r300/r300_context.c index 8f0effd83e2..7d6705058fe 100644 --- a/src/mesa/drivers/dri/r300/r300_context.c +++ b/src/mesa/drivers/dri/r300/r300_context.c @@ -327,6 +327,8 @@ GLboolean r300CreateContext(const __GLcontextModes * glVisual, ctx->Const.MaxDrawBuffers = 1; + _mesa_set_mvp_with_dp4( ctx, GL_TRUE ); + /* Initialize the software rasterizer and helper modules. */ _swrast_CreateContext(ctx); diff --git a/src/mesa/drivers/dri/radeon/radeon_context.c b/src/mesa/drivers/dri/radeon/radeon_context.c index ea81a3250b7..b67bda7d06a 100644 --- a/src/mesa/drivers/dri/radeon/radeon_context.c +++ b/src/mesa/drivers/dri/radeon/radeon_context.c @@ -355,6 +355,8 @@ radeonCreateContext( const __GLcontextModes *glVisual, ctx->Const.MaxDrawBuffers = 1; + _mesa_set_mvp_with_dp4( ctx, GL_TRUE ); + /* Initialize the software rasterizer and helper modules. */ _swrast_CreateContext( ctx );
