You probably should not be playing games if they literally make you vomit, you might have some type of medical condition. No, they don't make you a better player, because I've personally tested it. I was playing bf3 at 50 fps, I turned the settings down to get over 60 and it made zero difference whatsover. Any latency that you notice is due to your INTERNET CONNECTION. No human being can notice a latency of 2ms for god sakes. That's kind of why ping is good at anything less than 100. These are just percentages of one second we are talking here. I'm not saying the game may not look a little smoother at 60/80/120 fps, I'm just saying the difference once you get past 40 fps are NEGLIGABLE. Not anything that's going to drastically effect you gaming experience. The difference is in your head, the mind is a very powerful thing.
So, I assume you vomit everywhere, when you are playing your friends console games then? Consoles play at 30 fps and you don't here them complaining about framerate in droves like the PC crowd. Using a mouse makes no difference at all, the game is vastly different once you go below 30 fps, but anything above is a smooth playable picture in 99% of games. You want to shoot for around 40 just so you can account for fps dips. It's in your head save your money guys, you don't need quad sli 680s...
Just one, yeah I said one, 680 is enough to max any game in existence and still be a perfectly playable good gaming experience. At 1080p at least, which is the gaming standard. The only reason to get 680 SLI is for a multi-monitor set up or those uber resolution monitors.
Haha I just reread how you called a 2ms delat "horrible" you are truly insane my friend. I mean think about it 0ms is essentially instantaneous. So, your saying that you notice a 2/1000th of a second mouse delay, do you have robot eyes? Ah, you were talking about the polling rate, mine is 1000 so 1ms. Still, it's in your head or you have some seriously funky nausea problems that I've never heard of before, maybe your epileptic?
