Here are the keyboard only related problems that are reported but not fixed in many years
1- Alt/C Button getting stuck problem: This happens when you bind free camera function to these buttons. Game acts like you pressed free camera button, you can move around but can’t move your mouse to turn turret or control aircraft. You try to understand why game feels like you are pressing down free camera button. To clear, press these buttons…
2- Shift key getting ignored button: This also happens with other modifier buttons. Suddenly, modifier + normal key button works but shift key alone doesn’t work. I am using it for Sniper keybind in ground mode. Only way to fix it is clearing binding and rebinding.
3- Enter button getting recognized late bug: Seriously try this, you can reproduce it. Put your fingers both on Enter and T or Y button, which are default buttons for ingame circular radio menu. First press Enter, then quickly Y or T. You will see that Your chat field is opened for you to write but also team/squad menus are also open. This is clearly an input buffering issue where for some reason Enter button and T/Y buttons are treated equally, even if you pressed Enter before T/Y. Only way to clear this mess is pressing Esc twice to both close T/Y menu and chat window…
Rant over.
