Solid 30% GPU load on that page with layout.frame_rate=60, +20% when scrolling.
Solid 55% GPU load on that page with layout.frame_rate=120, +30% when scrolling.

It just makes me reconsider use of the layout.frame_rate with high values to improve smooth scrolling performance on this computer.
I noticed mine was set to 240 after reading this post, so I set it to 60, and if I scroll a page up/down smoothly by pressing down the middle mouse button so scrolling is locked it seems to slightly jerk on a timer every second or so, cpu isnt saturated. If I reset the value to default which is -1 it does the same as 60, but the jerk dissapears when on 240 again, odd?
Also I see no cpu usage difference between -1, 60 and 240. but on -1 and 60 gpu is about 33%, on 240 its 50%.
I changed back to 240 now, here is why.
