Body

We are working on pycharm (2025.2.0.1) in windows10 VDI, and upgrade the github copilot plugin to latest version (1.5.56-243). since the upgrade, we see major performance issue, and the pycharm is getting stuck and works very slow. after we downgrade to 1.5.55-243, it works well.
In addition, it seems like the models got "dumber" resulting in lower quality output. We got quite a lot results with incomplete or broken code and repetitive mistakes. Once we rolled back the plugin to version 1.5.53 everything seems to be in order again.

Not just in PyCharm, @arielman2304 in WebStorm is also poorly optimized. after having Github Copilot for a while opened, CPU goes crazy and I have to manually close it and open it again. (WebStorm 2025.2.1 - Github Copilot 1.5.56-243, MacOS)

in my experience in VSCode, there was no slowing down and models are ever improving, Claude Sonnet 4 hits the sweet spot of not being too aggressive and now with good reasoning, unlike the Claude Sonnet 3.7 where it scans and edit a lot of files that sometimes are well beyond what you want

but anyways, there are cases like yours too, so these might be the related issues that might be of help :

1. VS Code Plugin (Version 1.82.51)

• Reported by: Users on GitHub Discussions.
• Issues: After upgrading to version 1.82.51, users observed high CPU usage, with the rg process consuming over 500% CPU on Apple M1 MacBook Pro systems. This issue was particularly noticeable when working on larger projects, rendering the GitHub Copilot extension nearly unusable.

2. VS Code Insiders Version

• Reported by: Users on Reddit.
• Issues: Users reported that GitHub Copilot in VS Code Insiders was significantly slower compared to other code editors like Cursor and Windsurf. The delay in code suggestions was noticeable, leading to a less efficient coding experience.
