Troubles with point component preview

Hi! I’m new to Grasshopper and during my first tutorial sessions I met the problem with point component preview. When I place the component, no cross red cross points appear in Rhino view port. Rhino point appears only when component is baked. I’ve played with preview options – nothing helped. Any ideas?

Thanks in advance!

Try to switch on (or off) opengl sprites in the view menu.

If you have openGL sprites off, you might want to update your graphics card drivers. OpenGL sprites will draw themselves faster than the manual drawing that will be used instead. Not a huge deal either way, but it may make a difference if you have a few hundred/thousand points that need to be draw.
