Sadly linux framebuffer is still inferior in comparison to Windows framebuffer

I'm running Windows 7 with a 14 yo gfx card (ATI Radeon 9250 - DirectX 8.1) along with Windows 2000 drivers in compatibility mode and if you exclude some minor tearing everything else is perfect.

Same configuration but this time in linux, on various distros, from the lightest to the heaviest and the results are the opposite. heavy screen tearing and choppy scrolling everywhere, and the weird thing is that i see more Graphic Features enabled in the chrome://gpu/ in linux than i see in windows on this ancient card, yet the overall performance is inferior in linux.
