Can you by chance run a profile from the performance tab in the NUI dev tools?
Press F8 while in the menu, type nui_devtools, press Enter, Alt-Tab into the window that opened up, go to the Performance tab, click the Record button, then stop recording after 10-ish seconds and click the ‘Save Profile’ button in the toolbar, finally upload the recorded file here.
This issue seems to occur for a small subset of people so there’s probably some JS code (or worse, the Chrome host itself?) being fluky somewhere for some.
Thanks! Meanwhile, can you try setting the ‘update channel’ in the FiveM settings to ‘Canary’, and then setting the new ‘reduce blur’ option to see if it improves it any?
This helps greatly. When set to ‘Backdrop only’ it cuts the CPU usage in half, and setting it to ‘No blur’ cuts that in half too from what I can see on a quick look at task manager
