This functionality was present in OFP and Arma, it would keep "open" the chat window a bit longer to show the same message the other players see. I have the feeling that it's still there, but hidden as soon as you go back to the multiplayer screen?

This is realistic for fixed amplification NV I think. However, in 2035 you would have tought technology has advanced a bit to have variable amplification...

This is not a troubleshooting section. Please refer to the forums.

What is your FPS with Vsync off? It caps to 30 (half monitor sync) whenever it's lower than 60 (your monitor rate). That's simply how Vsync works.

Not a bug: In Arma II this was a feature, It mimics the concealment they have form grass, that is not rendered at this distance. You should still be able to hit them in the area where you cannot see them though.

Furthermore, the colors of this complete site should be reworked. sometimes there is very little contrast in text and background. Also the weird shadow effect in the bug summary fields drive me nuts.
