Intellisense is very show to register changes and update syntax highlighting / underlining in Cursor IDE, often taking upwards of 5-10 seconds. Under the exact same circumstances and changes, VSCode is nearly instantaneous. At the very least, Cursor should prioritize intellisense over AI suggestions, but it seems like it does the opposite or otherwise there’s a memory leak. ---

I am experiencing this as well. I’m on cursor pro but using Cline extension with my anthropic key for most of my AI interactions because I’m getting way better results. If the intellisense doesn’t get fixed I might go back to VSCode and just use it with Cline. ---

Still the same problem half a year later. More detailed: I am working with a very small `transformers` codebase, I have `cursor tab` turned OFF. VSCode gives lightining fast intellisense autocomplete and cursor stalls for long enough (10s+ even on variables local to the function) that it basically doesn’t work. I tried restarting + using `ruff` but to no avail. If anyone has any solutions, that would be awesome! ---

My Cursor too. I can not believe it. I can code with zero AI as all I use AI for is a quick Google search or a quick glance at the official document. Can people code without Intellisense ? I doubt it. An IDE without fast Intellisense ? Insane. ---

@D_c_Binh_Nguy_n It may be best to contact the Creator of the extension to see if the performance can be improved since we are not the creators of that extension ---
