That should make some sense if you think about it. Because you aren't using 100% cpu, you know that in some way the card is the limiting factor. By turning off tcl you are unloading work from the card, thus perhaps making its life easier & allowing it go faster... But really, the difference is so small that it probably doesn't mean anything at all.
