Speed up viewport display for NVIDIA card

Blender 2.63a

Viewport performance on computer with NVIDIA card is quite slow. One way to increase speed is disable the double sided shading.

For every object, uncheck the box :

Really huge improvement.

A little bit cumbersome if you have lots of objects to do at once.

So, keep in mind to uncheck it immediately every time you create a new object.


I’ve found a script to do this for every objects in the scene. Just switch to text editor and paste in these codes:

import bpy
for ob in bpy.data.objects:
if ob.type == 'MESH' :
ob.data.show_double_sided = 0

and press runscript. (there should be a tab indent on 3rd line, and 2 tabs on 4th line – or you’ll get error when running the script)
