Hi Wen, The slow ribbon and atom rendering must be a graphics driver issue. Surfaces use different OpenGL calls for rendering allowing them to be fast. You can try updating your graphics driver. If you have the most recent you could try poking around with graphics driver settings that trade of speed and quality. We don't have a 64-bit Windows Chimera. Only 64-bit Linux Chimera is available. We'll probably put out a 64-bit Mac Chimera in about 6 months and 64-bit Windows Chimera in about 1 year.

Hi Tom. I recently set up a Windows 7 64bit system for Nvision stereo display and ran into some problems with Chimera. First, the performance for pdb molecules (ribbon and atoms) is very slow. It seems fine with volume data (surface). Do you have any clue? Second, there is only 32bit version for Chimera and it cannot deal with large map. Do you have a 64bit version for Windows? Thanks,
Wen
