For quite a while, my movement keys have been sort of jittering/stuttering. For ex, I would press the W to key move forward, the character would move forward a bit and then stop even if I'm still holding the key down and this jittery motion would continue with sometimes the W key not responding at all. This has also happened before with my D key and it doesn't seem like a problem with my keyboard as other games are working and taking the input just fine. Any input would be appreciated.
