I have a speedlink rapax keyboard and for some reason, now it won't detect pressing X when W is down. So, obviously I can't crouch at the same time in-game when moving, thus slowing me down to first stop and then crouch and move again. It's happening in every game too, Battlefield 3/4, Insurgency, Arma 3/Project Argo... The keyboard is a cheapo "gaming" keyboard so obviously anti-ghosting is not supported. But it worked before! Should I open this up and take a look?
