Hi Tommi, That is true, but it is also the most extreme comparison possible. A crude estimate of the ranking of drivers would be:
NVIDIA > Intel (these are open source by default) > AMD > radeon (open source amd) > Nouveau (open source nvidia) While both NVIDIA and AMD hardware are of similar speed (trying to avoid flame war), both are faster than the Intel hardware. But with the open source modern intel drivers (i.e. near current mesa (I think we are at 10.3)). On any of the recent Intel hardware you should have more than enough gpu ooomph for freeview. (as an example. You can try it out on a friend's macbook air. The current intel linux drivers are faster than the mac drivers and freeview runs great on a macbook air).
