My primary PC is a notebook, so it's even less of a choice than with desktops...Nvidia. AMD makes great hardware too, but their drivers have always been sub par. I don't understand why it's okay to say that now (when they're actually probably less sub-par than they have been) but it wasn't 10, 15 years ago when the issues were just as bad if not worse LOL
Anyway, I fully respect AMD's hardware as also awesome, but I just don't have issues with Nvidia drivers, going all the way back to the TNT 1 in 1997/8ish.
For notebooks, Nvidia has for years tried to get it so any notebook can just install their regular (notebook) drivers, BUT even today not all notebooks can, and in fact the Alienware Alpha desktop can't install Nvidia's drivers, making it worthless (nice job Dell).
On top of that, while Nvidia's Optimus works better than I expected, it still causes issues, and is IMO pointless at best, and it's SUPER hard to find notebooks that don't use it. My 2013 Alienware it's togglable, but that's not the case for most. AMD's Enduro is their equivalent, and...yeah, it works as well as you'd expect, which is not at all. Even with Optimus I'm getting semi-frequent crashes in Dead Rising 2 and Assassin's Creed III.
I wish integrated video had never happened. Intel's GPUs are less of a joke than ever, but if you care about games at all, you want a dedicated GPU, and at that point you DON'T want Optimus/Enduro, and you DON'T want hundreds of millions of transistors spent on a redundant GPU on the CPU, which could instead be extra cores!
So yeah, the whole situation pisses me off. Less awful if you're on a desktop, but I realistically need a notebook, so get to struggle each time to find one that takes Nvidia's normal drivers and doesn't have Optimus *sigh*.
