Hello. Tried this suggestion today (setting "__GL_MaxFramesAllowed=1" in /etc/environment, and rebooting). It might have decreased my CPU usage, I am not certain. However what I am sure of is that it does no fix the 60hz framerate issue with multiple monitors, on NVIDIA.

So have now reported the bug over on NVIDIA's forum. With links back to here:
