I'm trying use the program Blender to create a great images from my structures. But, when i will render, the PC starting a lagging.
So, wich good program can I use to make good imagens?
I has a protein and a bilayer.
Have a look at the Pymol Gallery. As @genomax2 said, you are probably not using it correctly. You can import individual frames from your trajectory and work on an appropriate rendering style that you can then replicate for other frames/simulations.
