Return of Reckoning

I get random lag spikes during combat and i know it is not my hardware. any help would be great.

Not a lot you can do tbh. Just the standard stuff, make sure you don´t run any programs in the background, stop all internet traffic that uses a lot of bandwidth while playing. You could also try disabling your antivirus solution while playing or some products like ESET32 have a special gaming mode to activate.

Otherwise, there are a lot of players playing and Warhammer wasn´t a game responding well to that, even on live. Try to go to zones that are less populated or you could try to play scenarios but if the whole server is overwhelmed, log out and play something else for a bit.
