From fc8a8789da457aa1ebde2e66b4adf00dcda8d82a Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Sat, 5 Jan 2019 02:16:28 -0300 Subject: gl_rasterizer_cache: Use GL_STREAM_COPY for PBOs Since the data is doing the path CPU -> GPU -> GPU copy is the most approximate hint. Using GL_STREAM_DRAW generated a performance warning on Nvidia's stack. Changing this hint removed the warning. --- src/video_core/renderer_opengl/gl_rasterizer_cache.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src') diff --git a/src/video_core/renderer_opengl/gl_rasterizer_cache.cpp b/src/video_core/renderer_opengl/gl_rasterizer_cache.cpp index d3dcb9a46..bff0c65cd 100644 --- a/src/video_core/renderer_opengl/gl_rasterizer_cache.cpp +++ b/src/video_core/renderer_opengl/gl_rasterizer_cache.cpp @@ -452,7 +452,7 @@ static void CopySurface(const Surface& src_surface, const Surface& dst_surface, const std::size_t buffer_size = std::max(src_params.size_in_bytes, dst_params.size_in_bytes); glBindBuffer(GL_PIXEL_PACK_BUFFER, copy_pbo_handle); - glBufferData(GL_PIXEL_PACK_BUFFER, buffer_size, nullptr, GL_STREAM_DRAW); + glBufferData(GL_PIXEL_PACK_BUFFER, buffer_size, nullptr, GL_STREAM_COPY); if (source_format.compressed) { glGetCompressedTextureImage(src_surface->Texture().handle, src_attachment, static_cast(src_params.size_in_bytes), nullptr); -- cgit v1.2.3
