Dear James,

Thank you for your help! I tried versions 364.19, 352.79, 340.96, and none
of them worked. Finally, I tried version 304.131 and it worked! (although
my graphics card is listed as supported under all versions). Later I
realized that command nvidia-detect could check which driver should be
installed.

And NVidia driver solved the slow pymol problem!

Thanks for the help,
Chen
