There was an issue in the beta where zooming in, iron sighting, etc with a weapon kept your existing mouse sensitivity instead of halfing it like every shooting game does. It makes for a very difficult aiming experience.

This was addressed and patched in beta, but the issue seems to be back in the full version. Please fix this Crytek.

I agree. ADS sensitivity does seem really off. I know they patched it in beta, but it still seemed off.

Yes. The game is really amazing, but man its annoying to aim while zoomed. It was fixed in beta, idk how its back. Ideally a separate sensitivity bar for "while zoomed" would be great.
