What OS are you running? I currently have three Jetbrains IDEs open on my MacBook (M3 Max/36GB) and don’t notice any issue (although I don’t have any electron apps running which probably helps).
MacOS. I have Slack, Teams (different clients use different chat apps), Notion, Docker Desktop VM, several browser tabs, some corporate machine management stuff, and probably some things I'm forgetting about, all open all the time.
