Hi all,

1)
i just wondered if antialiasing is going supported in the OSX VMD1.8.1
Since the aqua interface does lots of antialiasing, the OSX is well
surely well geared for it,
and It would look soooo nice on my flat panel LCD iMac with the NVIDIA
GeForce2 MX.
Shame that the nice new ribbons don't have nice edges....

should there be more open GL extensions available than the ones listed
in my VMD startup below?
Am I doing something wrong.
BTW the native interface looks super! Nice anti aliased menus etc.

2)
On my linux machine (ATI RADEON 8500 64 Mb, athalon 2 GHz, RedHat 8.0,
Xig summit2.2 Xserver)
  I see the rendering performance (fps) drops drastically after the
openGL window is made larger than a certain size.
This does not happen with the OSX version, or with pymol or Bodil on
the linux machine.
Is this something to do with the video memory getting filled up and VMD
having to use virtual memory?
and if so why does it not happen with the other software such as pymol

Do I just need to tweak my settings?

cheers

Dan
