3D games (I don't mean games played with glasses in THREE-DEEEE) are useless for lag tests. They factor in some lag to begin with, and have their own - waiting for vsync, triple-buffering, upscaling, blah blah blah. Using 2D, sprite-based or vector-based games shows you everything you need to know.
It's like those people in the TV forums - "I hate this TV, it shows pixelation when the football players move."
Right, as if the tightly compressed satellite feeds have nothing
to do with that! People are mostly ignorant, and see what they see, not knowing what causes it. Using a "television" source to check your display device is asinine, just like using upscaled, 3D, wireless-controller-driven games to test input lag is asinine as well.
Some of you are clearly delusional and are actually hurting people - someone is going to read "Yep, the 3010 has no lag, feels perfect to me, I game all the time and I know what's good and bad," and then buy it, hate
it, and can't return it. That's a disservice, and it's not fair to the majority of readers here. Someone is going to drop almost $2000 to find out they've been lied to.
The 3010 and 5010 have horrible lag, end of story. Everyone defending it, please stop. Just because you "can't feel it" doesn't mean it doesn't exist. Do some screenshot proofs and you will see - science beats personal opinion.
