Keyboard / mouse ghosting issue ( not reacting when they should do )

There seems to be an issue with having to many input at once causing you to have to push the button again …

often this happens when i switch from walking left to right and at the same time try to switch from one weapon to another or reloading or changing to health pack. This makes the game over all feel really bad when you dont jump when you want to or reload or change items that you want in a fire fight
