Display Settings
Global display settings affecting rendering speed and quality can be edited through the 3D View Properties window.
3D View Size: changes the 3d view size.
Anti Aliasing: increase the number of samples for better looking pictures with little or no jaggies(i.e. steps in diagonal lines or edges); note that each sample is a complete redraw, so rendering time will increase linearly with the number of samples

| Anti-aliasing on | Anti-aliasing off |
Depth peeling: these parameters affect the rendering of transparent surfaces.
When rendering multiple transparent surfaces increase the Max peels parameter until you can see all the overlapping transparent surfaces; change the Occlusion ratio parameter to increase rendering speed or eliminate rendering artifacts:
0 = best quality, 1 = max speed
