With release of 5.4 patch, many people are faced with some problems. One of them is extremely low FPS (around 4-6) in dungeons\raids. This happens even to those, who have around 100 FPS in the cities with Ultra settings. I tried to disable all addons, delete "Interface","WTF" and "Cache" folders, but it didn't help. But after some research, I've found a solution:
1. Open the "World of Warcraft/WTF/Account_name" folder and find the file called "config-cache.wtf".
2. Open this file with any text editor.
3. Add this string to the end of the file: SET raidFramesDisplayIncomingHeals "1"
4. Save the file.
I hope it will be useful to someone.![]()
