/run PetRename(“name goes here“)

Fix disappearing nameplates

Try these different commands until the right combination fixes it for you. Just using the first one seems to work for a lot of people

/console bloattest 1 – Might make nameplates larger but it fixes the disappearing ones.
/console spreadnameplates 0 – Makes them overlap like they used to.
/console bloatnameplates 1 – Makes nameplates larger depending on threat percentage.
/console bloatthreat 1 – Makes nameplates resize depending on threat gain/loss. Only active when a mob has multiple units on its threat table.

Fix the cog of doom!

(Freezes/disconnects from mousing over things such as the Headless Horseman’s pumpkin, mage tables, feasts, etc.)

There’s tons of threads posted and lots of promising solutions. I have one that I’ve been testing for three days and have not had as much as lag spike when mousing over cogs. This works if you’re willing to disable tooltips when you are anywhere a cog icon might show up.

You will need to create two macros, for “turn off tooltips” and “turn on tooltips”.

Turn Off Tooltips

/script GameTooltip.Temphide = function() GameTooltip:Hide() end; GameTooltip:SetScript(“OnShow”, GameTooltip.Temphide);

Turn On Tooltips

/script GameTooltip:SetScript(“OnShow”, GameTooltip.Show);

(There have also been alternative solutions, such as using an addon like TipTac to replace your tooltips.)
