I played the beta last weekend, and this issue was not present. It started as soon as I escaped from my cell and the first skeletal warrior appeared, I can block whenever I want to but when It comes to attacking I must vigorously click the attack button at least 5-10 times before a single blow is delivered.
Im not lagging, everything else is fine. It's just when I want to attack. Any advice would be very much appreciated on how to fix this problem.
