Recently, I've been having a very strange problem with it. What is happening is that I will be in game (for example Bioshock Infinite) and I will hold down W to move forward, nothing will happen. I then release W and press another key and would most likely get the same result. However, a few seconds later it will go through with both my actions recently. I hope I have given you enough information and would like to know whether anyone knows what the problem is, thanks.
