may be because what we discussed here:

Undocking ATC with VSync HALVES fps (?)

I have to use vsync couse i hate tearing. And i do not have a gsync monitor. If you undock the ATC, the FPS are halved. Why? Is there a fix for this?

happens in your case too and so, because of limit the fps to a v-sync step, the GPU is no longer in full load.
