Sorry if this has been answered before, I've tried wikipedia to begin with then moved to google then moved to a forum search and couldn't find much.. I just got a GTX 280 and my old rig has new life I'm playing Left 4 Dead and feel like I can probably push higher than the 2x I was doing with my last card, but there are so many options! CSAA MSAA 16xQ CSAA I know the different multipliers are a case of "higher is better" but what about the other types? If anyone is generous enough to give a full explanation (or link to one) I'm very curious and would love learn more, but I'd be super grateful also for just a quick "this is the best looking option" answer, if there is a clear answer. Thank you in advance for any help!!
