Exteme Lag in cursor mid project! Help!

Beside this problem,just want to say editor is amazing and props to creaters.
It started lagging mid project i was doing and now its litterally unusable,delay of 7 secs when clicking on diffrent files,5 sec delay to type something in it ect. Im on pro version membership,using macbook m1 pro (it doesnt overheat or nothing) so im pretty sure its some kind of bug. Anyone have similar experience and has solution for it?

Do you have GitHub Copilot installed? If you uninstall it, does that help?

No i use copilot++ that comes with cursor. I really have no idea what caused lagging,could it be maybe docs i gave him to analyse?

Okay i figured it out. It was chat size that made everything slow and laggy,once I created new chat it was again normal.

Just curious, do you know how big your chat was? How many messages? Would want to fix this

Between 50-100 gpt4 requests, a lot, 2-3 days of coding. I remembered that open ai 3.5 also used to lag on big chat so I dont think theres something wrong with editor itself.

I see… we haven’t really optimized for the long-chat experience yet, but there are certainly a lot of things we can do to make it better!

I’m facing the same issue and I have no open chat, deleted all previous chats, disabled copilot++ - any recommendations? Love the app and just upgraded to the paid version but it is currently unusable…

I’m also facing the extreme lag. It just becomes unusable. I don’t have any chat OR any context that I provided to it. FYI, I’m on pro membership.

It’s the same here. It was working like a charm and suddenly became very laggy two days ago or so. It’s the same project/plugins, etc.

same here, can’t save file, add new line(the Enter key) but other keyboard typing is fine
after a while, it will suddenly response to my new line input, making lots of new lines.

Loving Cursor across the board, except that the lag makes it unusable for me as well. Adding my anecdotal story as a way to ping this thread.

I’m on a 2024 m3 mac pro and am getting up to 20s lag clicking through to open files, hitting save (prompting the linter / prettier to run), waiting for the typescript checker to figure stuff out.

It’s bad to the point that sometimes I’ll type out a variable name. I can see the red underline appear on the first letter (because the first letter isn’t a valid variable). Then two seconds later it gets to the next letter… and when it finally reaches the end of the var name it realizes that the variable is legit and disappears. I tell it that it’s ok and that it’s doing its best… but it’s really not ok.

Love the AI integration, but the lag is so far behind that it isn’t recommending anything to me anymore as I code. I’m now switching back to VSCode and copilot for regular coding, then back to Cursor for explicit chat driven AI.

Thanks for the product. Please prioritize these performance issues.

Also have this issue - is it possible to clear cache or something?

It’s happening on one project specifically but no others.

I’ve got the same issue – anyone have a solution? Keyboard input to the composer requires me to type at 1/2 speed. Macbook pro M2 max, 64gb memory, nothing else going on in the background. All other apps & even the code editor itself respond just fine; only composer.

Same issue - major lag in composer. Usually I start a new chat and that temporarily solves it but it doesn’t take long to be back in “lag world”.
M2 Macbook Air - 16gb memory - I typically have 6-7 other applications open and 100 tabs open in safari / chrome and they do not experience the lag, only the composer chat. Always takes it 5-7 seconds to “catch up” when I bring attention to it.

Downloaded cursor yesterday, got a pro membership because it refused to work at all without it. And now all i have is a mixture of increasingly HEAVY lags and “Tool call timed out”. Best is when the agent just fails mid way and leaves me with a broken codebase.

Its a shame this is what you get for paying for a product, that chat agent would be so cool if it actually worked on growing projects
