CheatEngine has a facility that you can basically slow down or speed up an game. It can be used for cheating, but it can also be simply used for game speed if you have issues with a games speed. So it is a cool little pc tool to take matters in your own hand. If the devs add something in great! If not, they you can just take it in your own. I run a 1.75x, feels good for both moving and combat speed. In this case everything is sped up 75%, not just you.
Pretty sure there are some quick Youtube videos to show how it works, basically start game, then start cheatengine, then pick the D:OS process in memory, then click speed hack and set your speed.
