I have terrible lag spikes/FPS drop when HonorBuddy attacks, but only when attacking. I am running an Acer Predator G3610, 8GB RAM, i5 3.0GHz Processor, 64-bit OS. Nvidia GeForce GTX 550 Ti Grahpics Card. WoW recommends High Quality Graphics, have tried running it on the lowest possible settings, but it is still the same results. 80 - 100 FPS WITHOUT HonorBuddy on, no animation or fights (spells etc) 50 - 60 FPS with big fights (Animation, spells etc.) WITH HonorBuddy on 40 - 50 FPS no fight. 5 - 10 FPS with honorbuddy on with fight, animation spells etc. Have you experienced this problem lately, because my problem occoured recently, but my graphics card has also been changed, but it was the same graphics card, just a new one.
Normally this is because your doing something wrong such as using Frame Lock in a CR that doesn't have it or using Frame Lock when the CR has it already enabled and you enabled it in Lazy Raider as well. But we can only guess until you post a log >.>
