[PD] Gem newbee question/antialiasing of edges on "boxes"

I use linux. in this OS, driver is more a problem than hardware.
so i used Nvidia because that was the only one that provide good driver (proprietary).

2 years ago, i was not able to choose the computer to use for a performance, so i had to use a ADM GPU. Driver did improve a lot and things where usable.
i did not try since.

since few years, nvidia had the optimus system for laptop that allow 2 GPU: intel and nvidia to work on the same time.
The intel GPU is for everyday use, the nvidia for graphical demanding application.
No real good drivers allow to use this on linux. So most of the time the nvidia is slower than the intel.

So i've got a optimus latop. I use the intel gpu most of the time for Gem. Even for performances.
but sometimes it's good to have the nvidia, for testing, and for non real time rendering.

So, looking only at the hardware :
nvidia and amd build low / medium and high end GPU.
intel did only do low end gpu.
but i'm still surprised by my intel HD4000 : working with shader, it's lot's faster than the mid range nvidia i used 3 years ago.

hope that help
