ReSharper C++ 2026.1: Better performance, improved Unreal Engine workflows, and language support updates | The ReSharper C++ Blog

ReSharper C++ 2026.1 introduces significant performance enhancements, particularly for large C++ codebases and Unreal Engine projects, with faster project indexing, reduced memory usage, and improved warm startup times. This release enhances coding assistance with features like auto-import for C++20 modules and expanded postfix completion while continuing support for modern C and C++ standards, including C++26/C23 and compiler-specific extensions. The update also improves Unreal Engine development by enhancing Blueprint integration, indexing Unreal Engine plugins by default, and ensuring compatibility with Unreal Engine 5.8. Additionally, new code analysis inspections help identify subtle issues earlier, and navigation tools have been refined to facilitate working with complex codebases. The editor UI sees improvements in tooltip support and scalable UI elements across different DPI settings, offering a cleaner and more consistent experience.
