August 8, 2019Aug 8, 201908/8/19This spring Gratian Lup described in his blog post the improvements for C++ game development in Visual Studio 2019. From Visual Studio 2019 version 16.0 to Visual Studio 2019 version 16.2 we’ve made some more improvements. On the Infiltrator Demo we’ve got 2–3% performance wins for the most CPU-intensive parts of the game.
July 30, 2019Jul 30, 201907/30/19In Visual Studio 2019 version 16.2 we improved the codegen of several standard library functions. Guided by your feedback on Developer Community (Inlining std::lldiv and Improved codegen for std::fmin, std::fmax, std::round, std::trunc) we focused on the variants of standard division (std::div,
July 25, 2019Jul 25, 201907/25/19On the C++ team we’ve heard loud and clear from users that build times are a pain point. We’ve continued our focus on improving the step, linking, that dominates F5 build times. Fast F5 build times, or iteration build times, are a key contributor to developer productivity and we felt that there was a large opportunity so we narrowed in on changes that we felt could move the needle 2x or more.

My name is Terry Mahaffey and I work on the code generation team in MSVC. Lately I’ve been doing some work on our inliner and I wanted to give a brief introduction to it before later diving into some of the changes we’ll be shipping.

Introduction
Last year we introduced Intel® Advanced Vector Extensions 512 (Intel® AVX-512) support in Microsoft* Visual Studio* 2017 through this VC++ blog post. In this follow-on post,
April 4, 2019Apr 4, 201904/4/19The March 2019 update of the Visual Studio Code C/C++ extension is now available. This release includes many new features and bug fixes, including IntelliSense caching, Build and Debug Active File, and configuration squiggles. For a full list of this release’s improvements,
March 27, 2019Mar 27, 201903/27/19In the era of ubiquitous AI applications there is an emerging demand of the compiler accelerating computation-intensive machine-learning code for existing hardware. Such code usually does mathematical computation like matrix transformation and manipulation and it is usually in the form of loops.
March 19, 2019Mar 19, 201903/19/19The C++ compiler in Visual Studio 2019 includes several new optimizations and improvements geared towards increasing the performance of games and making game developers more productive by reducing the compilation time of large projects. Although the focus of this blog post is on the game industry,

As C++ programs get larger and larger and the optimizer becomes more complex the compiler’s build time, or throughput, increasingly comes into focus. It’s something that needs to be continually addressed as new patterns emerge and take hold (such as “unity”
December 3, 2017Dec 3, 201712/3/17In this post, we’d like to give you an update on the significant progress the Visual C++ code optimizer made in the past year, focused mostly on the features released in the 15.3 and 15.5 versions. Compared to VS2015 Update 3,
