Is glxgears your only benchmark for establishing that 3D rendering is slow? If
so, it is most likely that it is a faulty benchmark as I am sure that 60FPS is
due to the FPS being synchronised to the VSYNC (refresh rate) of your TFT
(i.e. 60Hz).
Is it actually slower? What is the output of:
$ glxinfo | grep -e 'direct\|renderer'
