10-15 second lagg 2011 27” imac

Hey.

My GFs 2011 27" imac running osx 14.6.1 started having graphic glitches (screen tares kind of like no v-sync back in the day) and takes 10-15 seconds to respond to inputs. It was running fine for a few months and this just started.

Is there any known solution for this?

Thank you for reading.
