Gentapping, searching ruin whole match, "ruin OP"
The reason why survivors gentap and say "ruin OP" is low FPS and low monitor refresh rate combined with mouse/keyboard having high latency.
I speak from my own experience: When I had 40-60 fps on average with maximum 60hz refreshrate and a standard 10 bucks mouse, I was missing them greats a looot.
I cranked down my resolution and window size to achieve 80+ fps, overclocked my monitor to 85hz, got a new gaming mouse from logitech... And Now it's piss easy to hit them. Even 3 o'clock skillchecks are easy.
I think many who gen tap or run around the entire map to find ruin have difficulties to hit them ruin skillchecks because of one, two or all of the three aspects I mentioned above.
