Hi, I'm getting a new graphics card and thought that I'll run DDU in safe mode to get rid of any previous drivers. However now I realised that my monitor was a bit laggy as when a went into advances display settings it was set at 64 hertz and not 75 hertz without the option to change it. I dont know if DDU has done anything else to my computer but if you know how to fix my problem or let me know about any other things that may have happened please let me know thanks
