Strangly the most dangerous enemy in this gae is the controls, if i push the w key for too long it keeps walking and takes time for the character to stop, or if i attack too many times it sometimes keep continue attacking while im not pushing anything? sometimes my character does things on its own without me pushing anything whats happening?

Sorry this isn't the solution, but I havn't been having these issues, so it isn't a universal problem. How long does it take to stop the character when you let go of the W key?

depends on how long i pushed the button if i pushed it for long he keeps on running for a while, even had cheap deaths because of that because i kept on running and not attacking

Haved same problem. Solved by direct running the game application (not thorough the GOG launcher) with compatibility mode (windows 7 compatibility and run as administrator). You will not log your hours in game with a such way, but idk how to run with compatibility through the GOG launcher...

Try lowering the monitor resolution - that fixed the problem for me.
