Improving C++ Intellisense Performance with PCH

Thank you to everyone who has submitted feedback on the Visual Studio Release Candidate. We have received feedback that C++ Intellisense performance is slower. One way to improve this is to enable Pre-Compiled Headers usage for Intellisense parser. Andy Rich has written a detailed post on intellisense PCH usage that gives some additional details and explains how to optimize your intellisense engine with PCH. Here are a few of the benefits of using PCH:

·         Improves Intellisense parser performance in the IDE

·         iPCH is on by default as long as your project is using PCH


Thank you,
