Browser Scroll Performance

I’m seeing poor scroll speed performance in Firefox and Chronium. I used to be able to improve the situation by editing a few lines in about:config (firefox) but that no longer works. I’m guessing it’s an issue with the nvidia driver. If anyone has some useful tips they would be most welcome.

mozilla changed the way as to how scroll is handled.
