I doubt it, unless it will somehow make the drivers themselves faster.

Yeah, that's a fairly well known issue with the nvidia drivers, you
can also see that when e.g. comparing fps from running two glxgears
instances with running just a single instance. Running two instances
at the same time will get you much less than half the performance.
That issue may be unique to nvidia's setup, I don't get it with the
free r600 driver. Though it should be said that performance there
isn't quite at the level where it's fair to compare yet.
