Performance issue Fps Drop

Hello everyone I am new to warcraft logs however I have been searching and searching for an answer to my issue and have tried all the steps I could find. When using the " advanced combat logging ( so that my logs are rankable and live replay is there ) my Fps Drops significantly putting me at a disadvantage. I have a Solid pc and typically have no issues with the game. I have tried reducing all performance settings for the game to their lowest settings , clearing drive ( and defragging ) making sure drivers are all up to date and disabling any and all addons ( especially dps meters) all to no avail. so if anyone could tell me how I can do live logging without dropping below 60 fps constantly it would be greatly appreciated thanks!

If you are writing the log to a solid state drive, make sure the firmware of the drive is up to date.

nope it is a hard drive
