[PyMOL] High surface quality for large structures - hardware requirements

[Natalia <N.M...@hh...>]

Hello Pymol community!

I would like to be able to render high quality images of a surface representation of large structures, such as the ribosome. 
However when I set the surface quality to 2, on my machine it takes ages to get the surface representation.
Would a GPU be of any use to speed up this step, or is it used only in the rendering step?  Which would be the hardware requirements to speed this up and make it run more smoothly?

On our server (Linux) this process uses really little RAM and 1 thread, and after 2 hours it gives out the error message: CGO-Error: CGOCombineBeginEnd: invalid op=0x00 inside BEGIN/END
Does anyone know what it means?

I really wasn´t able to detect which hardware component is the bottleneck.
I would be very grateful if someone could help me out!

Cheers,

Natalia
