Hi can someone advise the most efficient defragmentation method (Folder, name, access) for the FS9 volume, especially, with respect to stutters, FPS.Thank youGhiom Vigui

Hi Ghiom, that sounds like O&O. If so, whatever you do, make sure you disable O&O's background service whilst simming if you you don't want to be periodically interrupted (typically every 60 or 120s). Hope this adds to thoughts, kind regards Jaap
