Did you see this:

I.e. it mostly affects the minimum framerate and smoothness for me as well.

Without the series, I get 70 average fps. With the series, I get 30 average
fps. That might just be random bad luck. I don't know. In any case, 30 fps
is really bad, so I don't think the series does what you think it does.
