Linear looks stepped. Please Help

Hi, I'm hoping someone could please help with a problem I'm having for a project….

Issue: The tangent in preferences is set to linear and the graph editor is set to linear, yet it looks like its in the stepped tangent. It looks mechanical, not sure how to make it flow/look natural.

Actions I have taken so far; -I tried switching to Spline and Auto Tangent, still looks stepped -Rebooting -Resetting Maya (Deleted Maya Pref)
