[Chimera-users] difficulty in using chimera for large PDB files

Dear Sir/Madam,

When we use chimera to visualize PDB files with ~18,000 atoms (PDB ID 5FUU) even
rotating the molecule is slow in chimera.
The computer has 6GB RAM. Would upgrading RAM help or we need to get a graphics
card installed?
Graphics card capacity should be 2GB or higher?

Could you please tell me the minimum computer configuration required by chimera
to handle large PDB files?
Also what is chimera's maximum limit for handling PDB files given a computer
with very good configuration?

Thank you.
