I have been playing Swordsman till now and this keeps happening frequently. Whenever I try to walking on anywhere when its about to lag, my character just keeps doing dashing action repeatedly within a sec and keeps go on like that till I stop. Sometimes to avoid this, I had to jump or sit but it comes back every times.
So … I assume that its my mechanical keyboard, Ducky One Brown Switch.
This is what happens whenever I put my character in the crazy of lag,The keyboard unexpected activates “USB repeat Acceleration”, Its a feature that allows user to adjust repeat delay and repeat rate under USB.
I simply just deactivate it every times this occurred, but it never ends.
