Venice Unleashed

We need smaller gun models, the iron sights take up way too much of the screen as it is, opinions?

Rather than smaller gun models, there should be not FOV change when the gun is aimed - that would be how you get realistic sized iron sights. It just makes the game harder!

The reason the iron sights take up so much of the screen is because of the zoom when you aim

Seeing how BF4 has this option and some of its advanced options like HUD and Radar scale already being confirmed to be possible in BF3, it's only a matter of time before such an option appears. That is, if someone makes it, of course

use 51 fov or around you will get same zoom aimed or not

You were close, the actual FOV for most weapons is 55.0f.

Tried to match it - Still, there is a scaling.The actual fov-value, that is set in the gamefiles, is different. https://youtu.be/qijK_mfRUPU
