From ad611383598387f16f4813654582b8d54f355c94 Mon Sep 17 00:00:00 2001 From: Subv Date: Sat, 22 Aug 2015 22:09:00 -0500 Subject: GPU: Implemented register 0x22A. This is the equivalent of the "first" parameter in glDrawArrays, it tells the GPU the vertex index at which to start rendering. Register 0x22A doesn't affect indexed rendering. --- src/video_core/command_processor.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/video_core/command_processor.cpp') diff --git a/src/video_core/command_processor.cpp b/src/video_core/command_processor.cpp index d82e20f86f..bfce080bb0 100644 --- a/src/video_core/command_processor.cpp +++ b/src/video_core/command_processor.cpp @@ -231,7 +231,8 @@ static void WritePicaReg(u32 id, u32 value, u32 mask) { for (unsigned int index = 0; index < regs.num_vertices; ++index) { - unsigned int vertex = is_indexed ?
