i asked many players like wax drill etc.
also i asked some osp players, my results are that u should have a fov between 95-110 (some people are using fov lowered by 5 on spacemaps)
if ur trained to u can play with an fov of 115+ i started e+ with an fov of 125, what is already very high.

also gameconfig can matter in this case

with right sens its easier to track an fast moving enemy with high fov,but a bit harder to hit.
with low fov u can easy shoot through small spots,if ur using highfov sound has to help with such "spots".

most good people are dropping there fov for railing better if u get used to ur dropped fov no problem.

so its all a question how long u play with that fov. (some1 who is using lowfov change to highfov he needs to train some weeks to get his old lowfov skills. other way round highfov players can aim a bit better with a new lowfov but they cant follow moving enemys)
also fov is a question of mousesettings cuz the cm for 360 degrees are changing with fov.

my personal fov is jumping like hell but u can think im using actually 95 up to 115.

if any "pr0gamer" thinks something is wrong in this text u can correct it

I am using 115 since the beginning.

These polls make a fine source for social analysis. Like the one with the toilet paper (most voted fold but few folders posted). I bet that low fov will win again and very few will admit having it.

I use 2 different settings

I use 90 for when I use rail and 105 for all other weaps I also lower my sens a small bit for rail.

112 still used by all weapons. I dont use zoom...
