C++ Dynamic Debugging: Full Debuggability for Optimized Builds
Over the past 5 years, we’ve had many incredible opportunities to engage with game developers. From AAA studios to indie developers, the passion for slashing iteration times is significant. Amidst all the fantastic feedback we've received for Visual Studio, one sentiment has rung loud and clear: a desire to debug optimized C++ code without sacrificing performance. Although game developers have voiced this need the loudest, we know that solving this issue will benefit many other C++ workflows. While we've consistently rolled out many productivity and performance enhancements over the years, debugging optimized cod...
Optimizing Build Times with Build Insights: How Activision Cut Call of Duty’s Build Time by 50%
Slow build times are a major headache for developers, especially in large, complex C++ codebases like game engines. Every minute spent waiting on a build is time that could be used to refine features, resolve issues, or push development forward. Activision faced this challenge with Call of Duty: Modern Warfare II, where prolonged build times were slowing down iteration and impeding workflows. By leveraging Build Insights, they identified key inefficiencies, optimized bottlenecks, and successfully reduced build times from 27:49 minutes to just 14:25 minutes—cutting them in half.
