Because I've used it, and the effects aren't being toggled off. I've even changed keybindings related to the F key. O_o
Aye, it's choices of things to remove does seem a little random, but it's selections are good. Keeps Cars, Pedestrians, Fog..
Turns off, Access Node Light beams, trash cans, code from dead NPCs, Combat effects, trails, Hyperjump landing "splash", Gunshot puffs, hacks etc. Probably more useful for Movies than screenshot editing, but certainly a nice option (and doesn't get rid of sound )
This doesn't work for me at all. I had Ctrl + F mapped to /face prior to the patch.. but even when I remove that keybind and restart, I still experience no change in effects when I hit Ctrl + F.
