Hey guys. I made this topic to help you get a better FPS following few steps.
First Step: Settings
You should configure your Firestorm.wtf file to get the better FPS. For your luck, I did it to you. You can download the best settings at attached files. With this settings, you will get the best FPS.
Second Step: Cache
Sometime your FPS decrease can be caused by the Cache folder; so delete it. This folder will re-appear after, so dont worry about. This folder is located at World of Warcraft Folder.
Third Step: Drivers
Is very important keep your drivers updated. Update Intel drivers clicking here, update Nvidia drivers clicking here and update AMD drivers clicking here. If you want know which drivers you need, type DxDiag in windows search bar and execute it. You will see a report about your computer.
Fourth Step: Addons
Like the drivers, is very important keep your addons updated or you can lose FPS. In wow curse you will find every updated addon. Go to wow curse clicking here and search your addon which you want update.
May this topic help you, cya!
