         | run at full speed again.

       | Flexible refresh rates would be a good idea. I have two that
       | exceed 144Hz at different points (160 and 165), there are
       | infinite more :p

       | "dots" for different rpms and there's an LED light which flashes
       | at a certain speed that then makes one row look more stable than
       | the others, indicating the speed.

       | or Firefox on Windows for me.

         | Do you have Reduced Motion turned on? Works for me in Firefox.
