Keyboard Input Delay since stormblood 6/16/17

[account_disabled]

I've been experiencing severe keyboard input delay. Pressing any button fails to yield a result until a full one second later. Given that I play on PC this is quite distressing as the game might as well be untouchable at the moment. At this point I've done everything I could think of: update drives, fiddle with graphics settings, and even switch keyboards. Short of an entirely different computer (which i do not have) I don't know what to do. Anyone else have a similar problem and maybe a solution?

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
