I am usually over 100+ fps in the lab, now down to 10 fps when not moving anything!
No settings have been changed, everything low, with object detail, textures, and environment set to medium.
Not sure if the change started after patch Tuesday or the hotfix yesterday.
I have run repair tool without any change.
addendum: V. Kerensky below seems to be right, restart seemed to bring it back to 60+ fps,
