leading has to do with a couple factors.
Yes, it's a physical factor as explained earlier, but here's the factors our high and mighty guy above forgot to mention
1) Server stability.
- - Here on aeria, which is shared by 200 other games, the server actually loves to play the random game, so your opponent MIGHt say he's 30 ping, but he could be acting like 90 due to really bad servers. While this is being over dramatic, the fact remains the server here on aeria contributes to the instabilities.
I never believed in anti lead until ijji was bought by aeria (sadly.)
2) Your PC OC/UC
Let's discuss this. For morons who DON'T know their computers, they think that overclocking and underclocking is cheating. Far from the fact, most every real gamer (who plays such things that you pay real money for, such as crysis 3, arma 2, batman arkham, Dirt 3, and whatever other game people quit gunz for) utilizes one of these to play their favorite games at optimum efficiency. I run my computer (a 3930k cpu on watercooling) at a nice n steady 4.6, instead of it's stock 3.2. So i enjoy watching my games in 1080p across 3 monitors (Such as shogun 2, arma 2, bioshock, ETC ETC)
Higher and lower frequencies changes how your computer sees gunz, and either helps or fails you. UC'ing your computer down to 1 or 2 cores will actually stabalize the amount you have to aim, while higher oc will increase the instability (Sometimes I'll hit at 1/2 a body, sometimes 1 1/2 bodies on 40 ping for example in extreme cases).
