Hi,

after a kernel upgrade (to 3.6.6-1) on a Fedora 16 laptop (Intel Core
Duo, 4GB RAM, NVidia 8400M GS) we had to upgrade NVIDIA driver from
295.59 to 304.64. The result is a terribly slow VMD 1.9.1 (practically
unusable) displaying <8 fps with no molecule loaded!!!. Things slightly
improve with beta driver 310.14 (<=15 fps no mol loaded), but usability
is still rather poor (not fluid).

Previously, witn NVidia 295.XX drivers, VMD 1.9.1 worked flawlessly on
the same laptop. However, with 304.64 or 314.14 all other tested OpenGL
programs works correctly and no error message is issued in Xorg.log or
when starting VMD.

Moreover, VMD 1.9.1 works flawlessly on a Intel i7+NVidia Gt230M laptop
with the same FC16+kernel 3.6.6-1 +driver 304.64 combination.

Thanks in advance for any hint/help.

Pietro
