This is something we're looking into, but in the meantime you can find some discussion and some tips
here that may help, including possibly playing in fullscreen, rather than windowed mode, which has helped some folks who are seeing this.
It's also worth trying to go to settings > 3d and facegen, try selecting one of the options to limit the max frames per second (toward the bottom of the screen).
It probably doesn't matter specifically what you choose here, just that you do choose one of the limited options (144 being the max) and not 'no limitation'.
