I find aliasing excessive and therefore too distracting and disturbing in 3D view, while today’s vga-cards are more than capable to anti-alias perfectly with almost no performance drop. So, is there a way to enable anti-aliasing -even by switching to another free realtime renderer (for 3D view) if necessary?
There are no antialiasing controls in Blender as far as I know. To enable antialiasing for the 3d viewports you have to do it through your video card’s control panel. Here’s what I did for my AMD video card under Windows 7:
The only way to enable anti-aliasing is in your GFX driver setup. I am on linux and I can switch anti-aliasing on/off only for the whole system.
IIRC, in windows it is possible to switch anti-aliasing on/off separate for each software. Depends on your GFX card/driver.
Cheers, mib.

I tried this and it didn’t work so I opened this thread, but after your replies, I re-tried and found out that I had to restart Blender to make the graphics card changes applied, thanks!
I’m a happy modeller now since I’m only using Blender to model end export (no HQ rendering) 
Yes, forgot to write that you have to restart the program to apply antialiasing settings
It took a while for me too to figure that out at first!
